Reading and Understanding Code

Practice Makes Perfect

One of the best ways to prepare for AP Computer Science A is by reading lots of code! Don’t just write—analyze code samples, trace variables, and predict outputs before running the program.

Underline or highlight variable changes as you go.

  • Watch for tricky logic in loops and conditionals.
  • Try explaining code out loud as if teaching a friend.

These habits make it easier to tackle multiple-choice and free-response questions on the exam.

Examples

  • Tracing the value of a variable through several lines of code.

  • Predicting what a code snippet will print before running it.
