My simple trick is apart from preparing hard and praying even harder. I know I cannt finish all the questions so I aim at finishing half of the questions and make WISE guesses at the remaining questions. I make sure I answer all questions even if I have to guess, and I just don't guess any how. I try to eliminate the obviously wrong options before I take my guesses. And we all would have noticed from flourmills results that u have to score average in all the sections (verbal, arithmetic and abstract) . So if you score bellow average in any section you don't go thru. But really prayer is the KEY. But you must do your part. Simple.
