By Suman Tripathy For many students, myself included, their first exposure to Computer Science is through the AP Computer Science A course in high school. Advanced Placement (AP) courses are designed for high schoolers to learn subjects with the rigor, depth, and complexity of college classes. Taking AP classes can also boost a student's weighted GPA. The AP Computer Science A curriculum emphasizes the fundamental concepts and problem solving skills that Computer Science requires, using the Java programming language. It introduces basics like variables, loops, conditionals, and methods, along with object-oriented programming, data structures, algorithms, and software design strategies. Java is a widely used programming language, useful and multifaceted because it can support abstraction, encapsulation, and object-orientation, all of which are important concepts for software engineering. The official prerequisite for AP Computer Science A is first-year high school algebra, including function notation and other algebraic problem solving skills. Overall, the course recommends a solid foundation in mathematical reasoning. However, having worked with many students taking this course, we have found that some prior coding experience really helps students be successful in this course. At Juni, we recommend students who are new to programming start with our Python Level 1 and sometimes our Python Level 2 course before moving into Java. The College Board's AP Computer Science A ExamTo receive college credit, students must register to take the College Board AP exam through their school, administered in May of each year. In 2017, the College Board introduced a second computer science AP course, AP Computer Science Principles. Compared to AP Computer Science A, this course "focuses on the broader aspects of computing, including not only programming but also topics like the global impact of computing, the internet and cyber-security, and creativity" (College Board). At Juni, we only offer the AP Computer Science A course. The AP Computer Science A exam is a three hour test. The first half includes 40 multiple choice questions and accounts for 50% of the exam score. The second half includes four free response questions focused on program design, implementation, and problem solving, and it makes up the remaining 50% of the exam score. All of the questions on the AP exam involving coding use Java as the primary programming language, and test booklets include the Java Quick Reference that includes all of the accessible methods from the Java library that the AP exam may reference. Goals of the AP Computer Science curriculum include:
Score Recommendation 5 Extremely well qualified 4 Well qualified 3 Qualified 2 Possibly qualified 1 No recommendation Ways to PrepareMost students who take the AP Computer Science A take the course in high school. However, it is possible to self-study for the exam successfully. Thankfully, many great online resources exist for students! The College Board itself has numerous helpful materials. For example, they offer a compilation of various exam tips and tricks, in addition to a test bank of each year’s free response questions, multiple-choice, sample answers, and scoring guidelines to ensure transparency and fairness in grading. Barron's, another well-known test prep company, sells a great book for this course and offers an online practice exam as well. Johns Hopkins Center for Talented Youth also offers this as an online course. At Juni Learning, we offer AP Computer Science A as a course with a private instructor that covers all of the topics on the AP exam in depth. With our classes, students are paired one-on-one with an instructor who works on concepts and test prep, tailored to the student's specific needs. With us, some students fully self-study for the AP exam, while others are simply getting exposure to the material in preparation for the school year ahead. Our AP Computer Science A course is broken down into the following modules:
Advice From Former AP Computer Science StudentsWe asked Juni instructors who took AP Computer Science in high school on what they did to prepare for the AP exam and any advice that they would give current students. Here is some of their advice:
Final ThoughtsThere are many different resources and programs that can help students prepare for the AP Computer Science A exam. The best fit depends on the student's learning style and time constraints. Overall, the AP Computer Science A course is a great opportunity to learn the fundamentals of computer science and demonstrate proficiency to colleges. Passing the AP exam is a great way to earn some college credit, but more importantly it helps develop a lifelong technical skill that helps one think in new ways.

Next fall, she will be moving to New York to pursue her Master's in Data Science. She is currently a Senior Instructor at Juni Learning. You can often find her camped out at Philz Coffee reading books and listening to music!
