Yes. All our full length practice tests are adaptive and use the same algorithm as the ETS GRE, which means you will get to experience what the GRE is exactly like.
In addition to the full length practice tests, you can also choose to take adaptive quizzes on CrunchPrep, wherein a select number of questions from a set of topics you choose will appear in an adaptive manner, just as in any section of the GRE.
For instance, you can choose to take an adaptive practice session in all math topics, or just one topic like geometry. Ditto with verbal.
