I started my GRE prep with verbal, and I went over vocabulary before delving into prep questions. Dr Raju’s methodology of teaching with vocabulary cartoons with memory tricks is very popular in this part of the world. This book is an excellent resource for vocabulary found on the GRE. It's far more extensive than any other revised GRE vocabulary books. Once I started working on memory-check exercises, I found this list far more helpful than the other resources.
