A preview of real practice questions from the Wrexa Edge AP Computer Science A bank — the same style, phrasing and difficulty you'll face on test day. Full solutions unlock free inside the mock.
Section I — MCQ (42 Q) · Language — Strings
Q1. A StringBuilder differs from String because:
Why: Correct answer: D — StringBuilder is mutable; String is immutable. Topic: Language — Strings.
Section II — Free Response (4 Q · typed code) · Probability
Q2. Two fair dice are rolled. Find the probability that the sum is 7. Justify by listing outcomes.
Why: 6 favourable outcomes out of 36 = 1/6.
Section I — MCQ (42 Q) · Language — Strings
Q3. StringBuilder vs StringBuffer:
Why: Correct answer: A — StringBuilder is unsynchronised; StringBuffer is synchronised (thread-safe). Topic: Language — Strings.
Section II — Free Response (4 Q · typed code) · Calculus — Chain Rule
Q4. Differentiate f(x) = (3x² + 1)⁵ using the chain rule. Show each step.
Why: f'(x) = 5(3x²+1)⁴ · 6x = 30x(3x²+1)⁴.
Section I — MCQ (42 Q) · Language — Final
Q5. Java keyword "final" on a variable means:
Why: Correct answer: B — The reference (or primitive value) cannot be reassigned. Topic: Language — Final.
Section II — Free Response (4 Q · typed code) · Calculus — Product Rule
Q6. Differentiate f(x) = x²·eˣ using the product rule. Justify your method.
Why: f'(x) = 2x·eˣ + x²·eˣ = x·eˣ(2 + x).
