When you finish a 3.5 hour-long practice test, the last thing you want to do after scoring it is to go over the questions you got wrong. But reviewing practice tests is ridiculously important. It’s as valuable as taking the practice tests in the first place, if you go about it strategically.
First of all, don’t review your test right after you score it. You’re tired and frustrated – at least in my personal experience. I recommend reviewing each test the next day.
