well, i just read the book some 3 times. just memorize all the modals n know which one to apply when a certain type of info is given. apply 2 or even 3 if u can and have time. p3 wasnt hard to me at all. i took it easy n was scared after the paper k urr na jae, pata nai kasia hua hy but turned out this way.
but then, there are people who find it very hard. har kisi k liay har paper asan nai hy or har paper mushqil bhi nai hy. Dont worry u ll do great inshaALLAH
