I’m a Maths tutor (T-Leng Tuition). The thing I see most often is students who do 50 questions, get 20 wrong, check the answer at the back, and still don’t know why. So I built MugCorner, a practice site for Sec 1 to Sec 4 Maths (G1, G2, G3 and A-Math), to do what I’d do sitting next to them:

• Topical practice for every chapter, from easy to exam level. When an answer is wrong, it doesn’t just say “wrong”: it names the mistake (e.g. a sign error when expanding, or forgetting the ±).
• Stuck? A step-by-step guide breaks the question into steps and checks each one, so they find the exact line where they went off.
• WA practice papers on the chapters being tested, marked with where the marks went, then a short follow-up paper on just the weak spots.
• Revision reminders bring back topics they’re starting to forget, and a progress page shows which chapters are solid and which aren’t.
• Works on a phone or laptop, and can be added to the home screen like an app.

It follows the current MOE syllabus, and the questions are generated fresh, so students can’t just memorise answers. It’s free during early access:

The chapter notes, worksheets and exam-style papers are free to read and print without an account: mugcornersg.com/worksheets?ref=kp

It’s still early, so I’d really value feedback from parents and students: what’s useful, what’s confusing, and any question that looks wrong. Happy to answer questions here too.
