Thinking about pursuing Computer Science as a college major and want to get ahead? You might be interested in taking AP Computer Science A, as the course can help you earn college credit before you even set foot on a college campus; because they cover a lot of content very quickly and in great detail, AP courses may often seem intimidating; however, AP Computer Science A is a challenge that can be met if you are prepared for it, and after reading about the content the course covers, the structure of its AP exam, and some great resources you can make use of, you might feel prepared to take on this challenge.

AP Computer Science A is a course taught to advanced high school students that approaches the same content with the same rigor as a collegiate introduction to computer science course. In AP Computer Science A, students learn to code programs they have designed in order to solve problems; while doing this, they learn about standard algorithms and typical applications, as well as how to develop and analyze algorithms and fundamental data structures, along with how to use logic and formal methods and how to be responsible in their use of these systems. Upon successful completion of an AP Computer Science A class, students know how to successfully write, run, and debug computer programs, make use of common data structures and algorithms appropriately when problem-solving, code in Java and in a programming language that is based on objects, read and make sense of a big program made up of many classes of interacting objects as well as information about how the program was designed, and recognize the social and ethical implications of proper and improper computer use.

AP Computer Science A courses are usually capped with students taking the AP Computer Science A exam. Success on this exam can translate into college credit. The AP Computer Science A exam lasts for three hours and contains two sections of equal weight. The first section consists of 40 multiple-choice questions, and students are given seventy-five minutes to answer; the second section is made up of four free-response questions the student has one-hundred-and-five minutes to answer. An appendix that contains a quick reference to both the case study and the classes in the AP Java subset is provided on the exam. It is completely normal if you find yourself unable to answer each and every question on the AP Computer Science A exam, as the exam is meant to cover course content comprehensively, and thus may test a few topics that your specific class did not mention or stress.

If Computer Science A sounds like a class which you might take, or if you’re currently enrolled in a Computer Science A course, you may find Varsity Tutors’ free AP Computer Science A resources to be useful, in particular our free AP Computer Science A Practice Tests. Each Practice Test functions like a little multiple-choice quiz, and you can elect to answer questions drawn from various AP Computer Science A topics or from a single specific Computer Science A topic. After completing an AP Computer Science A Practice Test, you get to see how you did in comparison to others who answered the exact same questions, and how much time it took you to answer each question. You also get to see full explanations of how the correct answer for each problem was reached, so if you made a mistake, you can figure out where you went wrong and learn from your error. By making use of these resources, you can review efficiently and comprehensively and fill any looming gaps in your Computer Science A knowledge before you take your AP Computer Science A exam!

The difficulty level and the number of questions vary for each practice test. You’ll find each one takes a different amount of time to complete. Each AP Computer Science A review provides the same useful assessment at the end, including the percentage of practice test-takers you performed better than, your total score, the time spent on each question, a comparison to how others scored, and an overview of the questions and answers. If you got something wrong, an explanation is provided to help fine-tune the respective skills and assist you in refining your study strategy.

Varsity Tutors’ Learning Tools AP Computer Science A example questions are organized into separate tests by concept. Most of the practice tests are short; some only have one or two questions. Once you proceed through these, you’ll have the opportunity to take the practice quizzes, which primarily consist of 12-question problem sets. These also vary in difficulty, and take anywhere from a few seconds to several minutes to complete. Some of the topics covered include debugging, algorithm analysis, compiling, testing, programming, and data structures. You’ll also be tested on numerical representations and binary code. The practice tests also test your problem-solving skills, Java knowledge, and dealing with problems involving different classes of interacting objects.

Another asset on the website is the AP Computer Science A Full-Length Practice Test. This 40-question test offers a higher level of assessment. As test day draws closer, you can time your performance and endurance, track your scores, and get even more familiar with the format of the actual exam. Varsity Tutors’ Learning Tools AP Computer Science A sample questions are designed to test your abilities in college-level computer programming. You can run through the tests alone to build your skill set and confidence, or share your progress with others on social media. This makes the process that much more challenging and competitive. The more practice tests you take and the more involved you get in mastering all the skills, the better your chances of scoring well on the AP Computer Science A exam and succeeding at the college level are.

The TileGame problem from the 2009 AP Computer Science Exam is typical of free response problems that test Lists. The problem requires you to manipulate a List and the objects inside.

Review the TileGame free response problem with AP CS Tutor Brandon Horn.

TileGame Part (a): getIndexForFit

private int getIndexForFit(NumberTile tile) { if (board.size() == 0 || tile.getRight() == board.get(0).getLeft()) return 0; if (tile.getLeft() == board.get(board.size() - 1).getRight()) return board.size(); for(int i = 1; i < board.size(); i++) if(board.get(i - 1).getRight() == tile.getLeft() && board.get(i).getLeft() == tile.getRight()) return i; return -1; }

TileGame Part (b): insertTile

public boolean insertTile(NumberTile tile) { for (int i = 1; i <= 4; i++) { int index = getIndexForFit(tile); if (index != -1) { board.add(index, tile); return true; } tile.rotate(); } return false; }
