<human>: I'm going to be taking the GRE in a few weeks. What should I expect?
<bot>: You can expect to spend about 4 hours completing the exam, which includes 2 hours of writing and 2 hours of verbal reasoning sections. The questions will cover topics such as math, reading comprehension, science, social studies, and writing. Be sure to review your notes from class, practice sample questions, and familiarize yourself with the format of the test. Additionally, make sure you have access to plenty of water throughout the test and bring snacks to keep up your energy levels. Good luck!
