The Official Guide to the GRE Revised General Test (often abbreviated as OG) is the single most reliable resource for anyone preparing for the Graduate Record Examination. Published by Educational Testing Service (ETS), the organization that creates and administers the GRE, the guide offers authentic practice questions, detailed answer explanations, and insider tips that reflect the tests current format.
The book is divided into three main sections, mirroring the GREs structure:
Each practice set is accompanied by a detailed breakdown of why each answer is correct or incorrect, helping you identify specific weaknesses.
There are many commercial GRE prep books on the market, but the OG stands out for three reasons:
Start with one of the two full practice tests. Take it under timed conditions, using a computer if possible. Record your raw scores and, more importantly, note the question types that gave you trouble.
Return to the relevant chapter (Verbal, Quant, or Writing) and work through the practice sets that focus on those problem types. Use the explanations to understand not just the right answer but the reasoning process behind it.
After a week or two of focused practice, retake the second full-length test. Compare scores to your baseline; any improvement indicates your preparation is on track.
While the OG can carry most candidates to a competitive score, pairing it with additional resources can round out preparation:
Misconception 1: I dont need to do the full practice tests. The adaptive nature of the GRE means you cant reliably gauge your score without experiencing the computerbased format. The practice tests are the only way to simulate this behavior.
Misconception 2: The OG is too easy for highscoring students. While the difficulty curve mirrors the average test, the guide still includes hard items that appear in the top percentile. Moreover, the explanations teach the higherorder thinking required for those questions.
The Official Guide is available in several formats:
Preparation for the GRE need not be a guessing game. By using the Official Guide to the GRE Revised General Test as the backbone of your study plan, you gain direct access to the same material the test makers use. Combine disciplined practice, strategic review, and a realistic simulation of test conditions, and youll be well positioned to achieve a score that reflects your true potential.
Remember: consistency beats intensity. Set aside a regular study slot, track progress, and stay focused on improvement rather than perfection.
