This model is acceptable to use by UK examination boards, Eire may be different.

This calculator is as good as it gets for your child's Maths exams this summer. It will also see them through A Level Mathematics and Advanced level further Maths if that is one of their chosen A Level subjects.

This post is more about awareness rather than price. You can actually get it slightly cheaper from Amazon 3rd party seller.

For GCSE the FX-83/FX-85 are recommended and typically costs £5+
For AS / A-Level , this is the recommended calculator... yes, you could probably get away with using a cheaper one... but you would be making life much harder for yourself... it's an excellent calculator and money well spent.
Strange, my students pass A and AS level exams with a standard £5 calculator. I wouldnt recommend spending £26 on one.
Funny this should pop up my sons in year 10 and asked for a calculator that does fractions too. Anyone able to recommend one as im clueless in this department. Hes currently using my casio scientific one that i used in school that calculator was built to last still on the same battery!

I think BigAde is spot on. Unless there's going to be a disaster, my son will be taking at least 1 Mathematics A level together with other science based subjects so I went for the FX-991-S-UH
I'd check with the teacher first what they recommend... they will be teaching them how to use their calculators properly in lessons, so it makes sense to use the same calculator as the rest of the class. I ended up buying the FX85 for GCSE and then the FX-991EX for AS. Both are excellent calculators but it's horses for courses.

Only really need them for maths and physics exams, not much call for them in the others

Both the calculators you mention are the ones that the my son's school recommend and sell.
Graphical calcs are great for checking quadratics equations. Some now can transpose formula aswell as giving the working out. No good in an exam but great when you're learning on your own.

I can tell you clearly aren't a maths teacher.
It's not that this calculator is very different. A Standard calculator works just fine but will be dependent on the student on how he uses it. This calculator makes things as easy as legally allowed. I purchased this for GBP 20 on Amazon. Brand New
This calculator is great for degree students in a budget as it will solve linear, quadratic, cubic...equations as well as carry out operations on matrices amongst other things. When you are solving 3rd order ordinary differential equation in an exam, this calculator might be the difference between a fail and a pass or even a higher grade. It is a time saver when you are assessed on your ability to solve differential equations. This price is standard and not really a bargain. Did not vote either way.
