However, the advanced scientific calculator fx-991EX will give students an advantage for both learning and the exam in solving equations. Please see below to compare these calculators. All of the models mentioned above are allowed in any exam where calculators are permitted *; there is no distinction between a calculator for GCSE and one for A-level as far as JCQ (who make the exam regulations) are concerned. You can find the JCQ regulations in section 10 of this document. If you have the older GT Plus then it will still do everything you need for GCSE, so don’t worry about that! Until the current GCSE and A-level specifications came in (2015 and 2017 respectively), the standard calculator in most English schools for both GCSE and A-level for a good few years had been the Casio fx-83GT Plus – or the fx-85GT Plus, which was exactly the same except that it had a solar panel as well as battery power.

From the comments I’ve seen on social media from other Maths teachers, I’m far from alone in having a strong preference for the older Classwiz fx-83/85GT X and 991EX models over these new CW calculators. Casio doesn’t appear to have done much field testing of the new models before launching them on the world!When the new specifications came in, Casio brought out new upgraded calculators called the Classwiz series. The GCSE model was the Classwiz fx 83/85GT X, and included a few extra features that the GT Plus didn’t have, although the GT Plus was (and is) still perfectly adequate for GCSE. Students will need access to at least trigonometric functions. The minimum-requirement scientific calculator is the fx-83G CW or fx-85GT CW. These have all the functionality required for GCSE. However the advanced scientific calculator fx-991CW will give students an advantage for both learning and the exam in solving equations. Please see our model comparison to evaluate these calculators. Casio describes the fx-83GT CW as “the new upgraded version of the Casio fx-83GT X” and the fx-991CW as “the new upgraded version of the Casio fx-991 EX”. That seems misleading to me, when the models are so completely different. It would be far more honest to call them “the replacement for” their predecessors.
