Graphical calculators (specifically Fx-cg50)Watch
Ps. If anyone with experience with this model could tell me what other features it has I'd appreciate it greatly.
For AL Maths (Not Further Maths) and the sciences, I'd use the Classwiz FX-991EX. It's the same as above, but has the solar cells for around the same price. The CG50 is very good, but only necessary for Further Maths in my opinion.
