Do You Need a Calculator for GCSE Mathematics?

Are you looking for the best calculator for GCSE mathematicsGCSE mathematics and A-level mathematics? Look no further than the Casio FX-991EX. This calculator is the perfect choice for GCSE Maths, and it can even take you far in A-level math. It has all the functions and features needed to ace your GCSE Maths exams, and it's allowed on all GCSE, IGCSE and A calculator exams in the United Kingdom. If you have the right calculator and you know how to use it, you can avoid being among the 40.4% of students who don't pass their math tests.

This feature is especially useful if you plan to take A-Level Mathematics in college, but it can also be useful at the GCSE level. The Casio FX-85GT Plus still has great functionality (for a GCSE calculator) and will allow you to outperform your GCSE. If you want to leave math behind after school, you could probably leave this calculator together with it. For GCSE mathematics, you'll need a scientific calculator, but almost any model will do; see the AQA guide below for a list of the functions you need.

The biggest drawback of this calculator for GCSE compared to the FX-991 is that it doesn't have the equation solver. So if there's any chance you'll stick with Math beyond GCSE, then it's worth investing in a more advanced calculator like the Casio FX-991EX. If you are looking for a more detailed guide on calculators for student life after school, I have a useful article on the best calculator for level A math and additional level A mathematics.
