The following are the books and links for GRE preparation. I have sorted out the books based on the type of questions asked.
1) Reading comprehension: Its always better to be overprepared than be otherwise. Solve the Reading comprehension from KAPLAN. The passages are tough, but that will help you master the ‘RC” beast!
2) Analogies, antonyms, sentence completion: To be good at these questions, you have to be thorough with the wordlist. I would strongly recommend that you buy the BARRONS for GRE.
almost 90 % of the words come from the wordlist from BARRONS for GRE.
