🎯 Essential AP Test-Taking Strategies
- Predict Answer First: Before looking at options, predict what the code will do or output
- Slash the Trash: Eliminate obviously wrong answers to increase probability of guessing correctly
- Highlight Key Words: Look for "not," "except," "always," "never" — they change the entire question
- Trace Code Carefully: Step through loops and conditionals line-by-line
- Check Edge Cases: Test with empty arrays, null references, and boundary values
- Avoid All/None of Above: These options are rarely correct on the AP exam
- Make Options Parallel: If options differ in length or complexity, that might be a clue
