2. GRE Big Book by ETS

If you are looking for Data Analysis questions on the quant side and reading comprehension questions on the verbal side, then this is the best resource available. However, a word of caution: The questions in this book are based on the old GRE pattern (prior to 2011). Therefore, this book is NOT recommended as a primary resource of preparation; it should only be used for Reading Comprehension and Data Analysis portions.

4. The Manhattan 5 lb

It’s a book comprised of practice questions only. If you have exhausted the other resources in terms of practice questions, you can focus more on the quantitative sections (especially probability, statistics, and word problems) than on the verbal sections since the verbal section is not reflective of the questions and vocabulary you are likely to encounter in the real GRE test.

The downfall of these resources is that the practice questions on both verbal and quantitative sides are outdated. Similarly, the vocabulary of the verbal questions is very difficult and it is not the correct reflection of the real GRE test.

The set of 8 guides includes six guides for quantitative and two guides for verbal. This is the best resource to hone both your quantitative skills since it provides a comprehensive description of each section, loads of practice questions along effective strategies for approaching questions. The practice problems at the end of each topic are comprehensive and provide an in-depth explanation of answers. 

6. Magoosh

The Magoosh subscription comprises video tutorials for both verbal and quantitative sections of GRE. It’s a good resource for those users who have good fundamental concepts of both verbal and quantitative topics.

However, it’s not recommended for those students whose fundamentals are weak. If you are scoring less than 155 in each section of your GRE verbal and quant, then you should not use it, as it doesn’t focus on fundamental concepts.

7. Barrons GRE Guide

Although the guide provides numerous questions for practice, they do not reflect the difficulty level expected in the real test.
