Which is best book for Verbal ability?

Question

Verbal Ability includes following topics.

Verbal Ability : English Grammar, Sentence Completion, Verbal Analogies, Word Groups, Instructions, Critical Reasoning and Verbal Deduction. 

Answer 1

I think that is a difficult question to answer. Probably you can refer some GRE books- but that would be a bit too much for GATE. Usually the verbal questions asked in GATE are just a bit low standard compared to CAT exams. So, if you are not comfortable with verbal, you can prepare using CAT materials and avoiding tough ones.
