THE REAL CHALLENGE
Lots of students can code and still lose points on the AP exam
AP Computer Science A doesn’t only check that your program runs. It checks that you can write correct Java by yourself, with no compiler to catch your mistakes, and explain what code does just by reading it. That’s a different skill from building projects, and most classes don’t have time to practice it.
NO COMPILER
No compiler to save you
On the exam you type your code, but nothing runs it. A missing bracket, a wrong loop bound or a mixed-up == and .equals() can cost points you’d never lose in an IDE.
READ IT, DON’T RUN IT
Tracing code by hand
Much of the multiple choice shows you code and asks what it prints. If you can’t follow a nested loop line by line in your head, these questions eat your time.
INDEX 0
Off-by-one errors everywhere
Arrays, ArrayLists and 2D arrays all start at index 0. Starting at 1, or stopping one step too late, is the single most common way students lose points.
AP CSP
The Create task sneaks up on CSP students
In AP CS Principles, the program you build in class feeds straight into questions on exam day. Students who rush it, or don’t truly understand their own code, pay for it twice.
START HERE
AP Computer Science A and Principles, explained in plain English
Two College Board courses, two very different exams. Here’s what each one covers and how it’s tested.
01
What is AP Computer Science A?
AP Computer Science A — “AP CSA” — is a College Board course in programming with Java. It matches a first-semester college programming course. Students learn to write and read code with objects, conditions, loops, classes, arrays, ArrayLists and 2D arrays. The current course has four units, and the exam is scored from 1 to 5.
02
How the AP Computer Science A exam works
The AP CSA exam is fully digital and taken in the College Board’s Bluebook app. Section I is multiple choice: 1 hour and 30 minutes, worth 55% of your score. Section II is four free-response questions in 1 hour and 30 minutes, worth 45%. You type your Java code, but it isn’t compiled or run, and a Java Quick Reference is available throughout. Calculators aren’t allowed.
03
What is AP Computer Science Principles?
AP Computer Science Principles — “AP CSP” — is a broader College Board course about how computing works and how it shapes the world. It covers programming, data, the internet, cybersecurity and the impact of computing. Students can use any programming language in class. The AP score comes from a multiple-choice exam plus the Create performance task: a program each student builds, then answers questions about on exam day.

WHY ONLINE WORKS
One-to-one online lessons, built for the way code is learned
Programming is learned by writing code, line by line, with someone who spots the bug the moment you type it. A shared code editor does exactly that. Searching for an AP computer science tutor near me makes sense — but the best AP CS tutor for your course is rarely on your street. Online, your choice isn’t limited by your zip code.
🌍
A programming specialist, wherever you live
In San Jose, Waterloo or Munich, you learn with someone who teaches Java and computer science every week — not a general tutor who covers it now and then.
🖥️
The same code, on the same screen
You type, your tutor watches each line. A wrong loop condition gets caught as you write it, not after twenty minutes of confused debugging.
⌨️
Practice without a compiler, on purpose
We build real programs in an IDE, then write exam-style answers in a plain editor with no autocomplete and nothing to run, just like the exam.
🗓️
Lessons that fit a busy schedule
Around school, sports, other APs and robotics club. Evening and weekend slots in US and Canadian time zones, plus after-school times in Europe and the Gulf.
HOW IT WORKS
From your first program to a calm test day
A simple path, shaped around your course, your school’s pace and the score you’re aiming for.
01
Free trial and diagnosis
We look at your recent tests or code, write and trace a few short programs together, and find the exact topics and habits costing you points.
02
Your plan
A week-by-week plan matched to your school’s unit order, your course (CSA, CSP or both) and the May exam — and, for CSP, your Create task deadline.
03
Weekly one-to-one lessons
Each lesson mixes one idea, live coding and real exam practice. You leave knowing exactly what to practice before next time.
04
The exam run-in
From early spring: timed free-response sets, code-tracing drills and full practice exams, until test day feels familiar.
A TYPICAL AP COMPUTER SCIENCE A YEAR WITH US
September and October
Unit 1: objects, methods, the String and Math classes. We build careful habits with types and method calls from day one.
November and December
Unit 2: if statements and loops. Lots of tracing, because this is where off-by-one errors start.
January and February
Unit 3: writing your own classes, constructors and methods. Class Design free-response practice starts here.
March
Unit 4: arrays, ArrayLists, 2D arrays, text files and data sets — the biggest unit on the exam.
April to early May
Full practice exams, all four free-response types under time, and a last pass on your weakest unit.
Starting late?
We shrink the plan to the units and question types worth the most points: data collections and the four free-response patterns.
WHAT WE COVER
Every AP Computer Science A unit, and where students lose points in each
The current AP Computer Science A course has four units. Here’s what each one covers, its share of the multiple-choice section, and the mistake we see most often — because knowing where points go is half the battle.
UNIT 1
15–25%
Using objects and methods
Variables and types, expressions, calling methods, and the String and Math classes.
WHERE POINTS GO
Integer division (7 / 2 is 3, not 3.5) and comparing strings with == instead of .equals().
UNIT 2
25–35%
Selection and iteration
if statements, Boolean logic, while and for loops, nested loops and common loop patterns.
WHERE POINTS GO
Off-by-one loop bounds and confusing && with || when a condition is negated.
UNIT 3
10–18%
Class creation
Writing your own classes: instance variables, constructors, methods, this, static, and how to design a class from a description.
WHERE POINTS GO
Forgetting to initialize instance variables in the constructor, or making them public.
UNIT 4
30–40%
Data collections
Arrays, ArrayLists and 2D arrays, searching and sorting, reading text files and working with data sets, and tracing recursive methods.
WHERE POINTS GO
Removing items from an ArrayList inside a forward loop, which skips the next item.
The four free-response questions we drill
The four free-response questions follow the same patterns every time. We practice each one until the setup feels automatic.
FRQ 1
Methods and control structures
Write one or two methods using loops and if statements, often working with String methods.
Where points go: A loop that’s correct for most inputs but fails at the first or last character.
FRQ 2
Class design
Write a whole class from a description: its variables, constructor and methods.
Where points go: A missing or wrong method header, and instance variables that aren’t private.
FRQ 3
Data analysis with ArrayList
Work through an ArrayList of objects to find, count, filter or change items.
Where points go: Removing or adding items while looping, and calling methods on the wrong object.
FRQ 4
2D array
Loop through rows and columns of a 2D array to search, total or rearrange values.
Where points go: Swapping rows and columns, and going out of bounds on the last row.
TEST DAY
Writing code with no compiler
On the exam, you type your answers in Bluebook, but your code is never compiled or run. Readers score what you meant to write, and the Java Quick Reference lists the classes and methods you’re allowed to rely on. In lessons we practice the habits that matter here: neat indentation, clear variable names, checking loop bounds by hand, and tracing your own code before you move on.
COURSE UPDATE
What’s no longer in AP Computer Science A
The course was updated, and some older study guides and tutoring sites are out of date. In the current course:
OUT
Designing inheritance is out. You no longer write subclasses with extends and super, and polymorphism questions are gone. You only need to know that every class is a subclass of Object.
OUT
Writing recursive code is out. You still need to trace recursive methods and say what they return.
IN
New topics are in: reading text files with File and Scanner, working with data sets, and thinking about data ethics and how AI is changing coding.
If your textbook or practice site still has an inheritance unit, ask us — we’ll help you skip what’s no longer tested.
AP COMPUTER SCIENCE PRINCIPLES
AP Computer Science Principles tutoring, from big ideas to the Create task
AP Computer Science Principles is built around five big ideas. Algorithms and programming is the largest share of the multiple choice:
BIG IDEA
1
Creative development
How programs are planned, built, tested and improved, often in teams.
WHERE POINTS GO
Mixing up a program’s purpose with what it does.
BIG IDEA
2
Data
Binary, compression, and how data is collected and used to find patterns.
WHERE POINTS GO
Lossy vs. lossless compression questions, and overflow in binary.
BIG IDEA
3
Largest share of the multiple choice
Algorithms and programming
Variables, lists, conditions, loops, procedures and simulations, written in the exam’s pseudocode.
WHERE POINTS GO
Forgetting that lists in AP CSP pseudocode start at index 1, not 0.
BIG IDEA
4
Computer systems and networks
How the internet works: packets, protocols, routing, fault tolerance and parallel computing.
WHERE POINTS GO
Questions on why the internet keeps working when a connection fails.
BIG IDEA
5
Impact of computing
Privacy, security, bias, the digital divide and how computing changes society.
WHERE POINTS GO
Vague answers about “good and bad effects” that don’t name a specific one.
AP CSP · PERFORMANCE TASK
The Create performance task
In class, each student builds their own program and submits three things through the AP Digital Portfolio: the program code, a short video of it running, and a Personalized Project Reference — screenshots of their own list and procedure code. On exam day, students answer written-response questions about that program, with their Personalized Project Reference in front of them.
SUBMIT 1
Program code
SUBMIT 2
A short video of it running
SUBMIT 3
Personalized Project Reference
EXAM DAY
Written responses on exam day
Where points go: a procedure that doesn’t really use its parameter, a list that isn’t needed, and written answers that describe what the program does instead of how the code works.
EXAM REFERENCE SHEET
The exam reference sheet
The CSP exam uses its own pseudocode, in text and block form, on a reference sheet you can use throughout. We practice reading it until it feels as natural as the language you code in at school.
HOW WE COACH
We teach the concepts. You write the code.
Our AP CSP tutoring covers all five big ideas for the multiple choice, and coaches you through the Create task the right way: we teach the concepts, review your plan and ask the questions that help you understand your own code. You write the program and the answers yourself.
YOUR TUTOR
AP Computer Science tutors who write and teach code every week
You’re matched with a programming specialist, not a generalist covering five subjects. Our AP Computer Science tutors come from the same team that teaches IB Computer Science — a course full of hand-traced algorithms and timed coding questions — so Java, data structures and debugging are everyday work for them.
💻
Programming specialists
Comfortable across AP CSA and AP CSP, from your first for loop to a 2D array search, with the depth to answer the “but why does it do that?” questions textbooks skip.
📝
They know how the exam is scored
The free-response patterns, what readers look for in typed code with no compiler, the Java Quick Reference, and the CSP Create task rules.
🧠
They teach you to think like a programmer
Patient when you’re new to code, demanding when you’re aiming for a 5, and focused on you writing clean, correct code on your own.
WHO IT’S FOR
Built for every kind of AP Computer Science student
From the student who’s never written a line of code to the one chasing a 5 in CSA, there’s a plan for you.
01
The complete beginner
AP CSA can be your first coding class. We go slowly where it matters — types, methods, loops — so the first unit test doesn’t knock your confidence.
02
The student who codes for fun but struggles on tests
You can build apps, but tracing code by hand and writing Java with no compiler feel strange. We practice exactly that.
03
The CSP student with a Create task due
We help you choose a project that fits the requirements, understand every line of your own code, and prepare for the written questions on exam day.
04
The future engineer taking CSA and calculus
Two demanding STEM APs at once. We keep your CS plan steady so it doesn’t fall behind your math.
05
The international-school student
Taking AP at an American school in London, The Hague, Dubai or Singapore, or switching over from IB Computer Science or Python. We teach Java and the AP exam, in your time zone.

WHY WE EXIST
Hand-picked programming specialists, one student at a time
Educifly began with a simple problem. As an IB Mathematics educator, Richa saw bright students lose marks — not because they lacked ability, but because nobody taught them how the exam actually works. Good, specialist tutoring was hard to find, especially online.
She doesn’t teach computer science herself. Instead, she hand-picks every tutor on our AP Computer Science team, looking for the same thing she looks for in a math tutor: someone who knows the course deeply and can explain it simply. The goal is simple: a student in Austin, Vancouver or Madrid gets the same quality of teaching as one in a big test-prep hub — one student at a time.

What does an AP Computer Science A tutor do?
An AP Computer Science A tutor teaches the AP CSA course one-to-one and gets you ready for the May exam. At Educifly, that means writing and tracing Java together, fixing weak units, and practicing the four free-response question types until you can write correct code with no compiler. Every lesson is live and online.
Do you tutor both AP Computer Science A and AP Computer Science Principles?
Yes. We tutor AP Computer Science A and AP Computer Science Principles. CSA students focus on Java and the four free-response questions. CSP students get help with the five big ideas, the pseudocode on the exam, and the Create performance task.
What is on the AP Computer Science A exam?
The exam has two sections, each 1 hour and 30 minutes. Section I is multiple choice and is worth 55% of your score. Section II is four free-response questions where you write Java code, worth 45%. The questions cover all four units, and data collections — arrays, ArrayLists and 2D arrays — carry the most weight.
What are the four AP Computer Science A free-response questions?
The four free-response questions are Methods and Control Structures, Class Design, Data Analysis with ArrayList, and 2D Array. Each one asks you to write Java code from a description. They follow the same patterns every year, which is why focused practice on each type pays off.
What changed in the AP Computer Science A course?
The course now has four units instead of ten. Designing inheritance and writing recursive code are no longer tested, though you still trace recursive methods. Reading text files, working with data sets, and data ethics were added. If a study guide still has an inheritance unit, it’s out of date.
Is the AP Computer Science A exam on a computer?
Yes. AP Computer Science A is a fully digital exam, taken in the College Board’s Bluebook app. You type your free-response code, but it isn’t compiled or run, so mistakes aren’t flagged for you. A Java Quick Reference is available throughout the exam.
Which programming language does AP Computer Science A use?
AP Computer Science A uses Java. AP Computer Science Principles lets schools teach in any language, such as Python, JavaScript or a block-based language, and the CSP exam uses its own pseudocode, explained on a reference sheet.
What is the AP CSP Create performance task?
The Create performance task is a program each AP CSP student builds in class. Students submit the program code, a short video of it running, and a Personalized Project Reference showing their own list and procedure code. On exam day, they answer written questions about that program.
Will a tutor write my code for the Create task?
No. The Create task must be your own work, and College Board checks that you can explain your code. Your tutor teaches the concepts, reviews your plan, and asks the questions that help you understand every line. You write the program and the answers yourself.
Do I need coding experience before AP Computer Science A?
No. AP Computer Science A is designed as a first programming course, and many students start it with no coding at all. Strong algebra helps, because loops and conditions use the same logical thinking. A few lessons before the course starts can make the first unit much easier.
Is AP Computer Science Principles changing?
Yes. College Board has announced a redesign of AP Computer Science Principles, with more about artificial intelligence. We follow every College Board update and teach the version of the course your class is taking, including any changes to the Create task.
Can I use a calculator on the AP Computer Science exams?
No. Calculators aren’t allowed on the AP Computer Science A or AP Computer Science Principles exams, except as an approved accommodation. Neither exam needs one — the math is simple enough to do by hand.
When should my child start AP Computer Science tutoring?
The best time is early in the fall, before the first unit test, or over the summer before the course starts. Many families start in winter, when classes and ArrayLists get harder. Starting in spring still works — we focus on the units and free-response types worth the most points.
How many AP Computer Science lessons a week does a student need?
Most students do one hour a week, which is enough to stay ahead of class and fix problems while they’re small. Complete beginners, or CSP students close to their Create task deadline, often do two. In the weeks before the May exam, families usually add timed practice sessions.
How much does an online AP Computer Science tutor cost?
Educifly’s 1-on-1 online AP Computer Science tutoring costs $50–$150 USD per 60-minute session. Your rate depends on your tutor’s experience, your course (AP Computer Science A, AP Computer Science Principles or both) and whether you book an exam crash course. The first trial lesson is free and lasts 30 minutes. You can pay as you go, or buy a package for a lower price per session. Invoices are issued in your local currency, there are no hidden fees, and you can cancel anytime.
Why does AP Computer Science tutoring range from $50 to $150 per hour?
Three things set the rate. Tutor experience: a more experienced tutor costs more, and the most experienced specialists sit at the top of the range. Course: whether you take AP Computer Science A, AP Computer Science Principles or both shapes where you sit in the range. Timing: intensive pre-exam crash courses cost more than regular weekly lessons. We confirm your exact rate after the free trial, once your tutor is matched.
Do you offer package discounts on AP Computer Science tutoring?
Yes. You can pay as you go, session by session, or buy a package, which lowers your price per session. We share package options after your free trial, once we know how many sessions a week you need. Prices are listed in USD and invoices are issued in your local currency.
Is online AP Computer Science tutoring as good as in-person?
For coding, it’s often better. A shared code editor lets your tutor see every line you type and catch bugs as they happen. And online, you can work with a true AP Computer Science specialist instead of whoever happens to live nearby.
Do you tutor AP Computer Science students outside the US?
Yes. We teach AP Computer Science students in Canada and at American and international schools in Europe, the Middle East and Asia, including Toronto, Vancouver, London, The Hague, Dubai and Singapore. Lessons are scheduled in your local time zone.
What happens in the free trial lesson?
Your tutor writes and traces a few short programs with you, looks at a recent test if you have one, and finds the topics and habits costing you points. You leave with a clear plan, and you decide afterward whether to continue. No card, no contract, no pressure.
What if my tutor isn’t the right fit?
Tell us, and we’ll match you with another AP Computer Science specialist. The fit between student and tutor matters a lot when you’re learning to code, so we’d rather change early than let lessons drift.
