Don't worry too much for the maths. Expect very basic calculs such as divide, multipliate, adition, Square roots....
An ex: An aircraft is growing up to 30 000 ft at 3500ft/min. He's currently flying at 20 000ft, how long would it take for it to reach 30 000 ft?
(and it's all multiple choice)
i.e 2 : 5 is the cube root of.... (Then 4 possibilities)
They provide pen and paper.
I've studied law and economics for 4 years and found it very easy.
Good luck
