You have to calculate quickly on this exam. I didn’t really realize that until took my first practice examination. I was cruising along on problem number 25, with forty minutes left to go. No problem!
Then I looked at the upper corner of my screen and found that I still had ten problems to do! There are 35 problems on this exam! That is only a smidgen more than five minutes per problem! Aaaahhhhhhhhh!!!!!!!!!!
Practice your calculations. You need your time for problem solving: you don’t have time to recalculate when you get to a solution that is not one of the choices. Practice your calculations.
