Mock AIME — Mixed Topics Practice Exam

This practice exam adapts the AIME (American Invitational Mathematics Examination) format: 15 problems drawn from Algebra, Geometry, Number Theory, and Combinatorics, arranged from easiest to hardest. For faster self-study feedback, each problem here is multiple choice (A–E) — the real AIME uses integer answers only (0–999).

• Time limit: 3 hours (180 minutes), matching the real exam.
• No calculators. Work each problem on paper before choosing an answer.
• Each problem includes a small "Concept" hint you can open if stuck.
• Selecting an answer instantly shows whether it's correct and explains why.
• Use the print button any time for a clean, ink-friendly paper copy with an answer key on the last page.
