<human>: I'm going to be taking the GRE in a few weeks. What should I study?
<bot>: You should focus on your strongest subjects first and then move onto weaker ones. Make sure you understand basic concepts like fractions, percentages, ratios, decimals, and algebra. Also, practice with sample questions from previous exams or online resources. Additionally, familiarize yourself with the format of the test, so that you can plan ahead for it.
