Class 8 Science olympiad practice

Free practice questions for every Class 8 Science topic on the olympiad syllabus, aligned with NSTSE-style papers. Each session gives you an OMR-style answer sheet, an explanation after every answer, a scorecard, and fresh questions on every attempt. Missed questions come back on a review schedule until they stick. No ads, no accounts, works offline.

Every attempt generates fresh questions on the same syllabus topic: new numbers, new names and new word problems, so practice never repeats exactly. Each one is NSTSE-style multiple choice, and anything answered wrong joins the review bank automatically.
