Review: Latest Casio GCSE scientific calculator - This calculator, released in January 2019, is Casio's replacement for the fx 85 GT Plus, which has been the most popular calculator for GCSE Maths in the UK for some years. The new version has many similarities to the old, including its overall size and most functionality. The differences are (1) the carbon fibre look of the front, (2) an improved, larger and higher resolution display, (3) a faster processor, (4) 14 more functions, mostly statistics-related, and (5) tweaks to the configuration options including menus. It is still powered by the combination of a solar cell and a 2032 battery. Casio has also released the similar, and generally slightly cheaper, fx-83 GTX calculator, which differs only in that it has no solar panel, and uses 2 AA batteries. All the other functionality is identical, so this review can be considered to cover that calculator too. Note that this calculator is *not* suitable for A level Maths, which now requires some additional statistics functions in a calculator. Get the Casio fx-991EX or a graphics calculator for A level Maths. The fx-95 GTX is still fine for A level science subjects requiring a calculator. At university level, it's hard to generalise, but this calculator can be recommended for many courses that require one. What is the competition like? Casio's own fx-991EX has a number of additional functions and is suitable for A level Maths too (as mentioned above) and is allowed by all the exam boards for GCSE, although not all schools seem to have got the memo on this. The other mainstream manufacturers of suitable calculators for GCSE are Sharp and Texas Instruments, each of which have various decent models. While I love my HP calculators, they are not very competitive in this particular market. You probably do not want to buy a GCSE scientific calculator from anybody other than the first 3 manufacturers listed: there are very basic, even cheaper, scientific calculators around which are almost invariably a false economy. Casio dominates the GCSE calculator market with good reason. They produce robust cheap calculators with just the right level of functionality. I can see no reason why this new model wouldn't be the new best seller. In summary, if you already have a Casio fx-85GT Plus (or fx-83GT Plus) there's no urgent need to upgrade to this new one. But if you are buying a calculator for GCSE Maths for the first time, or replacing a lost one, this is the safe choice, and will be absolutely ubiquitous before long.

There are two almost identical models, this one with the solar panel and another which runs on batteries. Note you only get a basic instruction booklet, the full manual has to be downloaded from the casio web site. **Q: Where is the β€œSD” button on the new version of this calculator?** A: Use the key to enter the SD Mode when you want to perform statistical calculations using standard deviation. In the SD Mode and REG Mode, the key operates as the key. Always start data input with (CLR) (Scl) to clear statistical memory. **Q: My previous casio calculator had an arrow button to delete just the last digit typed-can this calculator delete one number without using the c or ac** A: On this Casio calculator there is a DEL button to do the same function you are describing, very easy!! **Q: Is this the same as the fx-85gt plus?** A: No this is a different model. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Latest Casio GCSE scientific calculator *by P***Y on 3 March 2019* This calculator, released in January 2019, is Casio's replacement for the fx 85 GT Plus, which has been the most popular calculator for GCSE Maths in the UK for some years.

Can not fault *by D***Y on 4 May 2020* As always from Casio, they never fail to make brilliant calculators! Throughout my academic career, I have always used Casio calculators, particularly the older β€œFX-83GT” model during my GCSE & A-Level Exams. Now in university, I decided to invest in a brand new calculator, this time choosing the newer β€œFX-85GTX” mode with a solar panel, hopefully making it last longer. Upon quick arrival, the calculator is packed very well, in a nice, compact box. It comes with a nice shell which matches the colour of the calculator to protect it when not in use, like the original! The calculator itself is very nice also! I like the newer dark grey colour, as opposed to the lighter grey colour of the older model. In addition, the pink β€˜ALPHA’ buttons are a nice touch! It comes with all the essential functions that would be required in GCSE, A Level and Higher Education exams (excluding A Level and Higher Mathematics, obviously). Overall, I would definitely recommend this product, especially for such a low price (at the time of this review it was Β£11.00)! ## Frequently Bought Together - Casio fx-85GTX Scientific Calculator, Black - Helix Oxford Maths Set with Storage Tin - 10 Piece Maths Equipment Set - Helix Oxford Twin Pack of Erasers, Oxford Blue, Large --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/100576226-casio-fx-85gtx-scientific-calculator-black](https://www.desertcart.kr/products/100576226-casio-fx-85gtx-scientific-calculator-black) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-08*
