Choose a short skill check or a full-length practice paper. Review the questions your child answered, missed or left blank, then plan what to practise next.
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.
See correct, incorrect and unanswered questions separately. Small samples help guide revision; they do not establish mastery, predict awards or decide course placement.
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.
