Hey, I did the IB before and I have the ti-84 plus ce and it's the calculator I know well. Am I allowed to use it in the Edexcel A-level maths exams or do I need to get a new calculator? I heard that I might have to put it in exam mode, if that's true does anyone know how to do that? Thanks!
It is expected that a calculator for A-Level Edexcel will be able to handle normal and binomial probability. i.e using Z values and calculating probabilities. If the Ti can do that and it does not have any banned features (unlikely) then it should be fine. However, do check with your centre.
