GRE prep books, even from the big prep companies, can be a mixed bag. They often have errors (sometimes LOTS of errors) and most contain problems and topics I’ve never seen on a GRE!
The three books I can wholeheartedly recommend are. . .
This book is chock full of good practice problems. The problems are grouped by subject. Struggling with prime factorization? Turn to that section for plenty of practice. (Each problem is fully explained.)
Or get the kindle version. After all, you’ll have to do all your work on scratch paper during the actual GRE. Might as well start practicing now.
BIG WARNING: The problem sets are arranged so that the first 20 or so problems are fairly easy. They are designed to make sure you have a handle on the concept. It’s only the last 5 problems or so that are actually similar in difficulty and feel to real GRE problems. DO NOT make the mistake of just working the first few problems in each section to see if you know how to do it. It won’t give you realistic expectations.
The Kaplan book has the best balance between clear explanations of techniques and plenty of practice.
Like all the books out there, it has its share of errors, but it has less than most. A kindle version is also available.
You can get the plus version, which has a couple of extra practice tests and some other offerings, like mobile access and videos, but, IMHO, all of that is not worth the extra money.
The Official Guide to the GRE General Test, 3rd Edition, from ETS
I used to not recommend this book because it seemed like so many of the problems didn’t even really feel like actual GRE problems. I’ve recently revised my assessment.
There are some great practice problems in here! Although, just like in most other GRE prep resources, there are some topics in this book neither I nor my students have EVER seen on the GRE.
In my class guide, I have a comprehensive list of exactly what’s on the GRE compiled by going back through actual released GREs, and by polling my students after they took the GRE to see if there was anything on their GRE that we didn’t cover in class. If they saw new material, I added it to the course!
Take a look here to find out more about my course and save days of GRE prep time by knowing exactly what to study.
