Number revision — frequently asked questions
Where should I start with Number?
Open the first sub-topic and watch the video or read the notes — then try a few practice questions before moving on. If you're already confident, jump straight into a sub-topic quiz to see where the gaps actually are.
How long does it take to revise Number?
Most students cover a topic in 2-4 focused sessions of around 45 minutes — one sub-topic per session, with a short quiz to finish. If a quiz report keeps flagging the same sub-topic, spend a session on it instead of moving on.
Are these Number resources enough to pass my exam?
Every sub-topic in the Edexcel Lower Secondary Mathematics (EM3) syllabus is covered on Tutopiya — notes, videos, worked examples, practice questions and AI-marked quizzes. If a specific sub-topic won't click, book a 1-on-1 tutor who specialises in this subject.
How do the AI-marked quizzes work for Number?
