Hi, I do AQA A-Level maths and recently purchased the Casio fx-991EX. Is this okay to use in my exams? Thanks

Cheers. This looks brilliant and will prove really useful to students as I suspect this calculator will be common among A level students. Just one note - slide 17 says the log base 10 button is gone: it's actually hiding on the Shift & minus button.

This is excellent thanks Jamie. Minor slip - you refer to 'mode' button rather than 'menu' in the slide for 'alpha' button.
