AP Computer Science A Overview
AP Computer Science A is equivalent to a one semester introductory course in computer science. Students program in Java, and learn problem solving, design strategies, algorithms, data structures, and more. The program teaches both object oriented and imperative programming techniques. Basic english and algebra skills are required for students interested in AP Computer Science.
We’ll cover the course, exams, and our picks for the best AP Computer Science A and Composition books, and Review Guides for test year 2020 below, but if you just can’t wait, here’s the short list:
Getting a jump start on college level studies in Computer Science can be extremely helpful for students interested in software engineering and other fields. Whatever your motivation for studying AP Computer Science A, we’re here to help you succeed!
A full Course Description for AP Computer Science A is available from collegeboard.org.
AP Computer Science A is taught in the Java programming language, and is equivalent to an introductory college Computer Science course. After taking AP Computer Science A, a student should be able to do the following:
- Design and implement solutions to programming problems.
- Use and implement common algorithms.
- Use existing and appropriate algorithms to solve new problems.
- Write solutions using an object oriented paradigm.
- Write, test, run and debug java programs.
- Read and interpret programs containing multiple classes and interacting objects.
- Understand the social and ethical implications of computer use.
AP Computer Science A includes a minimum of 20 hours of lab work in either individual or group setting. In the lab, students are expected to design a solution to a problem, implement it in java and test it, fix any errors that occur, and compare other solutions.
The use of Java is required in AP Computer Science A. Because the language has far more features than can be covered in a single introductory course, a subset of the language is used.
A typical AP Computer Science A course is broken up into 6 topics:
- Object Oriented Program Design
- Program Implementation
- Program Analysis
- Standard Data Structures
- Standard Operations and Algorithms
- Computing in Context
Students taking the AP Computer Science A Exam are responsible for demonstrating knowledge of the above mentioned skills and abilities. The student’s knowledge is assessed through a 3 hour exam containing questions in both multiple choice and free response format. The exam is broken up into 2 parts, with the each accounting for 50% of a final score between 1 and 5.
Section 1: Multiple Choice
- 90 minutes long, 40 questions
- Accounts for 50% of the final score
- Topics including: fundamentals, data structures, logic, algorithms, recursion, and software engineering
Points are awarded for each correct answer, and no points are subtracted for incorrect or unanswered questions.
Section 2: Free Response
- 90 minutes long and contains 4 long form questions
- Accounts for 50% of the final score
- Solve problems in Java using more extended reasoning
All questions should be answered using Java programming language. No points are subtracted for minor syntax errors.
For exam dates, refer to The College Board AP Calendar.
