    bd BARRON’S ESSENTIAL 5 As you review the content in this book and work toward earning that “5” on your AP Computer Science Principles Exam, here are five essentials that you MUST know above everything else: 1 Implement all programming requirements for the Create Performance Task. Your program does not need to be a masterpiece, but it does need to contain the requirements. Make sure your submitted program contains a procedure, parameters, list, iteration, selection, and sequence. Use examples provided in this book to familiarize yourself with how the coding requirements can be implemented in your program. A 5000-line program that does not contain all the requirements will score lower than a 19-line program that does. 2 Understand what you programmed and be able to answer College Board questions in the written report. While College Board questions are vague, what they expect for answers is extremely specific. No partial credit is given. Use the examples and nonexamples provided in this book to understand how the College Board wants you to answer the written questions. 3 Be aware of the rules of syntax for the pseudocode used on the multiple- choice exam. The programming language used on the exam is unique to the College Board and can conflict with the rules for the programming language you used in class. For example, the index of a list begins with 1

    on the exam but in many languages the index begins with 0. 4 Become familiar with the type of questions asked on the exam. For example, your multiple-choice exam will contain robot questions, tracing problems, finding error problems, converting number questions, looping questions, and others. Use the hundreds of example problems included in this book to prepare. 5 Understand the scope of questions used on the exam. Many topics on this exam are complex but what is tested on the exam is not complex. For example, the internet is a complex topic and could take months to cover to fully understand the topic. However, the scope and depth of internet questions included on this test are limited. This book only covers what is on the test.

    Preface This book is aimed at students taking the AP Computer Science Principles exam and is designed to help students prepare for exam topics, regardless of what computer language or method they were taught. The book provides in-depth instructions on how to complete the Create Performance Task with six complete written and coded examples. We have included sample responses that earn high scores and sample responses that earn low scores. The provided sample responses are intended to serve as guiding resources only. Do NOT copy the sample responses! The College Board does rigorous checks for plagiarism. The questions and examples all reflect the style of recent exam questions and cover the essential knowledge topics outlined by the College Board. For the benefit of students and instructors, we have included one diagnostic test and two practice exams in this book, with three more practice exams available online.

    Introduction General Information About the Exam The AP Computer Science Principles exam is a two-hour multiple-choice exam with 70 questions covering five Big Ideas accompanied by a performance task containing three submissions. The College Board recommends you submit your performance task on April 15, with a due date of approximately April 30. After your teacher sets up your College Board account, you will be able to submit your performance task starting December 3. I recommend you submit your performance task well before the April 30 deadline. Because the College Board is constantly tweaking the dates, check for current dates at https://apstudent.collegeboard.org/apcourse/ap-computer- science-principles Content of Class Performance task: 30% of AP Grade Guaranteed 12 hours of classroom time to finish Program Code Written Responses Video of at least one significant part of your program running End of Course exam: 70% of AP Grade 2 hours 70 multiple-choice questions, paper and pencil exam Creative Development 10-13%

    Data 17-22% Algorithms and Programming 30-35% Computer Systems and Networks 11-15% Impact of Computing 21-26% Some exam questions may be aligned to more than one learning objective. For example, a question on programming might implement an algorithm and contain an abstraction. Hints for Taking the Exam The Multiple-Choice Section The multiple-choice questions are worth 70% of your score and are administrated at the end of the school year. There is no penalty for wrong answers. So answer every question, even if you have to guess. You have a little more than 1.7 minutes per question. You should have enough time to answer all questions on this test, and you will most likely have enough time at the end to go back to difficult questions. The 70 questions are fatiguing. You should practice at least one of the sample tests given in one sitting. Robot and programming questions can be simplified by hand-tracing the code. People score the performance task, while the EOC exam is scored by machine. The test is independent of the computer language used, but there are both text-based programming questions and block-based programming questions. The Performance Task Details on how to create a College Board account and how to submit your performance task can be found at https://apstudent.collegeboard.org/takingtheexam/about-digital-portfolio Create Task Allow your own interests to drive your choice of computing program.
