The GRE is divided into two parts. Section 1 (verbal) and Section 2 (quantitative) are of medium skill level. If you score highly, on your first Verbal section, then you will get a harder second Verbal section. If you scored poorly on your first Verbal section, then your second Verbal section will be easier. The same process repeats for the Quantitative secion. The GRE adapts to your performance by addressing your performance on the first two sections of the test.
Harder Questions Count More
A result of the CAT testing format is that the harder problems count more than easier ones.
If you get into the "hard" section, you will have the opportunity to get a very high score. Students stuck in the easy sections might end up getting more questions correct in the second half of the test, but will still get a low score because the easy sections don't award as many points as the hard sections.
