I've noticed on the verbal MGMAT CATs that regardless of how well you do, you always tend to get a string of below-average (average being your appropriate skill level) questions towards the end of the exam. For example, in the tests that I've scored in the 95th-99th percentile in verbal, my last 6 or 7 questions are only 600-700 level questions and I might have even gotten a few 500-600 level ones.
Is this pattern an accurate reflection of what the real GMAT tests are like? Would it behoove me to allocate more time on the first 3/4 of the test knowing that the test is going to throw softies my way towards the end?
