The standard GCSE model in the UK for the past seven or eight years has been the Casio Classwiz fx-83/85GT X (centre in the image), though in early 2023 Casio brought out the fx-83/85GT CW, which is very different and which has replaced the GT X (despite a poor reception from UK Maths teachers).Example: (2 + 3) × (4 – 1) = 15 LINE (2+3)* (4-1= k Fraction Calculations How you should input fractions depends on the input/output format that is currently selected. I’m still using my beloved 1980s Casio fx-451 scientific calculator (which has absolutely minimal key presses even compared with the Casio Classwiz fx-83/85GT models: even the S-D button is an ‘extra-step annoyance’ for me).

At this time, the ] indicator appears to the left of the expression, indicating that it runs off the left side of the screen.

Battery • After removing the battery from the calculator, put it in a safe place where it will not get into the hands of small children and accidentally swallowed.It – or an equivalent – is certainly required for the Statistical Techniques option on the AQA spec. Its 12-digit, two-line display ensures ample space for complex calculations and eliminates the need for scrolling. The coordinate conversion (Pol, Rec) functions cannot be used for a number table generation function.

So if there’s any chance of you continuing with Maths beyond GCSE then it’s a worthwhile investment.

It’s also worth considering an A-level model, especially if you’re doing the Higher Tier and there’s a possibility that you might continue to study Maths in some form beyond GCSE. If you have the older GT Plus then it will still do everything you need for GCSE, so don’t worry about that!

Any of these – most of which start with TX-30 – are suitable for GCSE, though if you like to be able to enter your fractions as fractions then you’ll need one of the Multiview models.
