Marked like a real examiner

Write your answer as you would in the paper and it is marked point by point against a marking specification built from real past paper mark schemes. Every point is awarded or withheld on its own, and where a mark is missing you are shown the exact sentence that earns it.

From PSLE to A Levels

Live today: A Level H2 Physics, H2 Chemistry, H2 Biology, H2 Mathematics, H1 Physics and H1 Chemistry, and O Level Physics, Chemistry, Biology, A Math and E Math. Real past papers, marked point by point, and your own progress across every chapter.

For students

Answer real past year papers and get marked against the answer key on the spot, down to the keywords you missed. Ask Volt anything in your syllabus and get a related question to practise. Challenge any student head to head, and exchange the marks you earn for cash vouchers or gear in the app.

For teachers

Make teaching efficient. Every teacher gets a class link and code that ties students to them. See who is practising, where they lose marks, assign work by topic or by past year paper, and homework arrives marked for you to approve.
