Improving your GRE scores quickly requires a focused and strategic approach. Start by identifying your weak areas through a diagnostic test, and allocate more time to those sections. Prioritize high-yield content—focus on the most common question types and topics that frequently appear on the exam, especially in the verbal and quantitative sections. Time yourself while practicing to improve speed and accuracy, ensuring you can complete each section within the given time limits. Incorporate regular full-length practice tests to build endurance and familiarize yourself with the test's pacing. Use targeted study materials, like the Official Guide to the GRE and practice sets from reputable resources like Kaplan and Manhattan Prep, to get a feel for the actual test questions. Focus on improving test-taking strategies, such as eliminating obviously incorrect answers quickly, and practicing mental math for the quantitative section. Finally, review your mistakes after each practice session to understand where you went wrong and avoid repeating them. Consistency, focused practice, and refining your test-taking strategies will yield significant improvements in a short time.
