Science olympiad practice, classes 1 to 10

NSTSE-style science papers check whether a concept is truly understood, not memorised. Practise every class 1 to 10 science topic, from everyday observation in the early classes to the foundations of physics, chemistry and biology.

Aligned with NSTSE-style papers (Unified Council). Classes 1 to 3 practise one question at a time, with a second chance before the answer shows; classes 4 to 10 fill an OMR-style answer sheet and get an explanation after every answer. Missed questions come back on a review schedule until they stick. No ads, no accounts, works offline.
