The test has no science. Part one is math, verbal and spatials (90 questions in 30 min). Part 2 is Reading Comp (40 questions in 15 min). The goal is to move fast rather than take your time. Spend 10 sec on question. If you know it, answer it. If you don't, circle it and go on to the next. The reading comp is best done as 'read the question and scan for the answer.' Don't waste time reading the paragraphs- they are long and dry. Schedule yourself for the test quickly. If you miss a seat this month, call each week, especially the week of the test and see if anyone has cancelled. That is how I got my seat.
