The fastest way to find out what you really know is to answer questions on it. 25schools gives you thousands of revision questions sorted by level, grade, subject and topic, and marks every answer the moment you submit.
What you get
- Every level. Primary, secondary and college programmes. Secondary covers both the new Forms and the old Grades, so you revise exactly what your class is learning.
- Topic by topic. Open a subject, pick the topic you studied this week and practise just that, instead of guessing from a whole textbook.
- Instant marking. Multiple choice and true/false questions are marked straight away, so you learn from a mistake while the question is still fresh.
- Written answers too. Some topics ask you to explain in your own words. Those are marked in seconds with feedback.
- Points for every correct answer, which move you up the student leaderboard.
How to revise with quizzes
- Choose your level, then your grade or Form and your subject.
- Open a topic. Read the short overview if you need a reminder of what it covers.
- Answer the questions, then check which ones you got wrong and why.
- Repeat the topic a few days later. The second score shows whether it has stuck.
Why it works
Testing yourself is one of the best-proven ways to remember things: pulling an answer out of your memory makes it stronger than re-reading the same page. Short quizzes also show you, honestly, which topics you can already skip and which need another hour.
Every quiz you finish is saved, so you can track your progress subject by subject. When a topic keeps going wrong, read the study notes for it, then come back and try again.
Close to the exam
When you know your topics, move up to full papers. ECZ past papers show you the exact style and length of the real exam. Use quizzes to fix the weak spots a past paper uncovers.
Is it free?
Yes. Anyone can revise on 25schools for free; the free plan has a monthly limit on quizzes. If you revise every day, a learner plan removes the limit. You can compare them on the plans page.
