"I recently sat my GCSE maths exam, and I used another scientific calculator. I subsequently bought the Casio FX991ES and I should have bought one earlier. It is user friendly, fun to use and helps you understand calculations. This calculator is not necessarily an easy option for answering maths questions. The calculator helps you to apply what you know. Excellent for calculating fractions, and gives you the option of an answer in fraction or decimal form. Very useful indeed."
Yes, I recommend this product.

"Comes with an operating book which is written in very tiny fairy writing.
If I were designing a calculator with multiple operations I would make the print much larger on the actual calculator. To use at a desk where you are going to relax to use it.
If you are doing everyday basic sums, on the move then yes tiny is useful to slip in your pockets.
I am doing a self study as a mature student out of curiosity."
Yes, I recommend this product.

"You only need the extra features of this calculator if you're going to do really advanced stuff - A level and beyond. For most students one costing half as much will do all that is needed. A little more positive key press would have been nice. I've always though Casio was the best to use."
Yes, I recommend this product.
