Take one free 15-minute test. See their strengths, pinpoint the weak topics, and get used to the real exam format — laid out like a clear report card.
A score alone doesn't help. This tells you where your child actually stands — and what to do next.
15 minutes here tells you more than 100 random practice questions.
Every test ends with a full report — here's what your child gets the moment they finish.
One glance shows whether your child is in the TOP 10%, 20%, 50% — or needs to push. Olympiad tests are banded harder, so the picture is honest.
Green = strong, amber = wobbly, red = needs work. When a topic collapses, you see it instantly — no more spreading tutoring thin across everything.
Each weak topic links directly to the lesson that fixes it. We don't dump a catalogue on you; we tell you which three lessons to open first.
Each question is tagged by topic and knowledge point, so you can see where the gap is — not just that an answer was wrong.
Filter by subject, or browse them all. No sign-up to take a test; register to unlock the full knowledge-point report.
