Which calculator should I use?
The IB allows most graphic display calculators, so the best one is usually the one you already own or your school lends you. The TI-84 Plus CE, Casio fx-CG50/fx-CG100 and TI-Nspire CX are the three most common in IB classrooms, and every guide above covers all three side by side. Whichever you use, learn its statistics and equation-solving menus early: they save the most time in the exam.
