well get a SAT(for Business ) and prepare English from there,there is a list in that book,and 80% of the English portion comes from there,that leaves behind Math and Intelligence,SAT also has math portion do that too,and the rest you should prepare Trigonometry,Logarithms,Matrices,graphs and sequences from 9th and 10th book(all basics nothing complex here)And lastly the intelligence part is on you,you can't prepare that,you have to do that on the go as it is very basic.
PS: All this if you're going for NBS(Nust Bussiness School) in NUST,NOT Engineering. hope it helps.
