The Free Response Section accounts for 50% of the AP Computer Science Exam. Students may take a “code quickly, check later” approach to the problems, to their detriment. A deliberate and methodical approach is far more likely to result in correct solutions. Such an approach is especially important since the exam is taken on paper, without the aid of an IDE. With practice students can adopt an effective approach to the free response problems.
Tested topics with which all students should familiarize themselves are well known. Even individual questions are often trivial variations of questions from previous exams. Mastery of a relatively small set of techniques for manipulating arrays and lists offers a significant advantage on the exam. Problems that test inheritance and polymorphism often require little beyond the ability to apply a limited set of syntax rules. Problems that feature the GridWorld Case Study frequently test a predictable subset of the material in GridWorld.
