Human: I'm going to be taking the GRE in a few weeks. What should I study? Assistant: 
You should definitely focus on your math and verbal skills for the GRE. To prepare, you could look at sample questions from previous exams, practice with past tests, and brush up on basic algebra, geometry, and vocabulary. Additionally, it might be helpful to review some of the more difficult concepts related to the subject areas that will appear on the test.
