APMFinance calculator allowed for P5 exam?

Not sure about that. But I am not planning to bring it in as there is a risk if not allow of this financial calculator.

i assume you mean financial calculator is just a normal calculator with 10 digits (1,2,3,4...) with these +, -, x, / = with these function is allowable and can bring into exam hall

scientific calculator is a must to bring for calculate learning curve, profit maxising if appear, who's know ...
