The GMAT’s adaptive algorithm adjusts question difficulty based on your performance. Typically, test-takers start in the 555-605 range for Quant and Verbal. If you answer correctly, difficulty increases; if incorrect, it may drop. The algorithm isn’t purely linear, meaning a single wrong answer won’t drastically lower your score, but consecutive mistakes will.
Timing doesn’t directly affect difficulty selection, but if you run out of time, unanswered questions hurt your score significantly.
For Verbal, the order of question types is randomized—you might start with CR, RC. The sequence varies per test and isn’t fixed.
