GCSE - Casio Calculators


Students & Parents

You’ll need a scientific calculator for GCSE Maths. Scientific calculators handle standard arithmetic and then add extra functionality like cube roots, powers, statistics, trigonometry, and more. They are also very useful for other subjects such as Science, so one model covers all your subjects.

A basic scientific calculator is the minimum you require for exams. However, a more advanced model such as the fx-991CW will give you advantages for learning and in the exam, for example with solving equations. Compare the calculators below.

Maths is a visual subject. A graphic calculator allows you to draw graphs and statistical charts while doing the same calculations as on a scientific calculator. Some schools now use our fx-CG50 graphic calculator which gives a significant learning advantage, especially at the Higher tier.

Please see below on why it might be worth considering this calculator.

Should I Buy A Graphic Calculator?

Maths is a visual subject. A graphic calculator allows students to explore graphs. For example, you could plot a graph, find the coordinates where two graphs cross, or draw a data chart.

Graphic calculators make learning a lot easier and more fun. They also give an advantage in exams. We recommend the fx-CG50 calculator for more confident mathematicians, perhaps those taking the Higher tier. Our graphic calculators are allowed in GCSE exams.
