A scientific calculator (Units 1 and 3)
Any scientific calculator without a computer algebra system is fine. Most schools in Wales use a Casio, so a Casio means the buttons match what your teacher shows you. Practise with the one you’ll use in the exam, not a phone.
Casio fx-83GTCW (the standard school one) · Casio fx-991CW (more functions, worth it for Higher)
A maths set
Ruler, protractor and a pair of compasses that don’t wobble. Loci and constructions questions are free marks if your compasses hold their width.
Black pens, a pencil and a rubber
Write answers in black pen. Draw graphs and constructions in pencil so you can fix them.
A clear pencil case
Most exam centres ask for a see-through one.
What you don’t need to buy
Practice papers and questions. Every topic on TamzMaths is free, marked like the real exam, with a worked example for every type of question.
