Competition practice quizzes
Warm-up questions in the style of the big school competitions. Choose a level, answer by multiple choice or by writing the answer, and ask for a worked explanation whenever you get stuck.
Looking for a test rather than a quiz?
The adaptive practice test draws on a separate bank of nearly a thousand questions and changes difficulty as you answer, ending with an estimated level and a topic breakdown.
About these questions
Every question here is original, written for this site in the style and difficulty of the named competition. They are warm-ups, not past papers, so use them to build confidence and then work through the official materials:
- Math Kangaroo past papers — free official PDFs with answer keys
- MOEMS — Mathematical Olympiads for Elementary and Middle Schools
- Science Olympiad and Science Olympiad of California
- DOE National Science Bowl — official sample question sets
