Decoding AP Computer Science A: For a High Schooler, By a High Schooler

This is a required book for everyone taking AP Computer Science. There's no better textbook for the class, and it will prep you for the AP exam. The book is written by an AP Computer Science student, so it's written for high school computer science students. Not only will you have the best textbook, you get access to an online video course with lectures that will help you understand complex topics. There are practice tests in each chapter and prep questions for the AP exam.This course (like AP CompSci) is based on Java. If you aren't taking the course but want to learn Java programming, this book is for you, too.

I teach AP Computer Science and I congratulate Moksh on producing an excellent book. It covers the APCS-A course content well, and is clear and easy to read. Coupled with the Barron's APCS review book, any student will have very good resources to help them achieve. I plan to recommend this book to my students next year.

I'm a highschool senior, and this book has been a tremendous help. Put simply, I'm was already programming in Java and have the rules memorized a few days later! This book really makes it fun and easy to learn AP Computer Science. Thank you!

Wonderful book, it's not often that you see a study book written by an actual high school who has experienced the test and knows how his fellow classmates learn best!

I'd like to return the bookI and my kid found 5 errors in the chapter answers so far. Covered chapters for objects, polymorphism. I will post the errors on the errata page if there is such a page. I'd like to return the book.

While it is very impressive that this book was written by a high-school student, there are many errors in the examples, sample questions and answers. For instance: On figure 9.7, page 268, the figure atempts to illustrate how Mergesort works but while text says the result is sorted, the list in the figure remains unchanged. Another example -- there are at least two errors in the code for chapter 9 question 21 ("for" loop of j should start at i instead of 1 and that "for" loop never swaps the very last element). And one more (although there are many): The Answer Explanations for chapter 9, questions 22 is an answer for another question.Again, I comment the author for his efforts and kind heart. (He nobly states early on that he hopes to provide free copies of the book to anyone who can't afford it.) However, if you need to use this book to prepare for the AP Test, you are better off with Barrons. (I purchased both for my twin sons and we wound up purchasing a second copy of Barrons)

Amazing book with complete insight was the first reaction from my niece. I gifted it to her and happy to get attention to study AP Computer Science. Definitely, recommend for all students who wants to start learning computers as this was not an easy work for us to get her started.

"This Book was surprisingly comprehensive in its examples.As someone who wanted to drop APCS, I was pleasantly surprised by the excitement it brought to learning. Shoutout to this book for getting me through APCS"
