Built for the new GCSE. Not the old one.

In September 2025, Wales replaced its two maths GCSEs with one new qualification: GCSE Mathematics and Numeracy (Double Award). New units, new papers, new grades from A*A* to GG, and the first results in summer 2027.

Most revision sites and past papers were made for English exam boards, or for the old WJEC GCSEs. TamzMaths was built from the new WJEC specification and sample papers, question by question.

Everything on the paper

Revision they’ll actually come back to

Daily One MarkOne exam question a day, the same for everyone. One go. Share the result with your mates. Beat the clock60 seconds of quick non-calculator questions. Beat your best score.

Plus streaks, badges for real achievements, and a little sunshine when they get full marks.

How it works

  1. Take a 10-question check

    Pick a topic. A short check finds the right starting point, so nobody wastes time on what they already know.

  2. Climb the ladder

    Foundations, then exam-style practice, then A* questions. Four full-mark answers out of five moves them up a rung.

  3. Sit a full paper

    When they're ready, a timed practice paper shows exactly where the last few marks are hiding.

Hi, I'm Tamzid Choudhury.

Final-year BSc Mathematics and Computer Science, Swansea University

Most people call me Tamz. I grew up in Cardiff and sat my GCSEs in the same Welsh system your child is in now. I created TamzMaths using both halves of my degree: the maths behind every question, and the computing that marks each one the way a WJEC examiner would.

Why I built it

Extra help with maths has become expensive. A tutor for one hour a week usually costs £80 to £100 a month, and tuition centres often charge £75 or more a month for each subject, plus joining fees. With the cost of living the way it is, plenty of families can't stretch to that, even when their child is only a few marks from the grade they need.

The difference between CC and BB, or AA and A*A*, is often one mark. I want every student in Wales to have someone in their corner for that mark, whatever their family can afford. Every message your child sees on the site is written by me, the way I'd say it if I were sat next to them.

And thank you for being here. Whether you're a parent looking out for your child or a student taking your revision into your own hands, the fact that you've found your way to TamzMaths genuinely means a lot to me. I'd love to help.

Let's hunt that one mark together.
