Good calculator, great colour
Brought this calculator as a replacement for my daughter's one as someone took a liking to the one she had at her Secondary school, (and subsequently didn't return it). The calculator arrived on time and as specified. My daughter says it does exactly what is needed for GCSE Maths and loves the colour as it's not the black coloured one we usually go for (which is great as long as someone else doesn't "borrow" it again.)

Amazing calculator
Love it! I also love all the features it has. The quality is really good. I do prefer the sliding lids though. Also some of the functions you may need are in hidden menus which is annoying. Calculator works well. Price is standard for this. Design looks quite nice in blue. Battery yet to die!

This calculator doesn’t make you blue
My son who has just started at secondary school loves this calculator as it’s the same as everyone else but the only one who has it in blue. Easy to use and should get him through the next few years.

It does what the rest of them does (update)
It is easy to use however its not the model of calculator I would suggest you take as you’d be better off with the fx991ex if you are using it for high school however past that point I suggest you ask your teachers which calculators are allowed in the exams as past school there will be a lot more restrictions with the calculators and the model numbers as for uni I suggest you get the fx83gtx but if the price puts you off get it from eBay because although pricey it doesn’t have a cheap quality feel unlike the fx85gtcw and it doesn’t have missing functions and for anyone else who wants to buy this DON’T GET THIS ITS NOT WORTH IT sure it functions like a calculator but there are a few functions that are more important than others. My honest recommendations are the fx991ex for high school use or anything else and the fx83gtx past school aka College/ Sixth form and finally University (I would share pictures and videos of it but as I’m writing this I’m preparing this for returns if that doesn’t tell you something I don’t know what will).
