RC best resources

Hi Team,
I have GRE exam in 1 month. I have already covered following material for RC questions. However, I feel I need to solve relevant anf high wuality questions in remaining three months. Please suggest me book which has highly relevant RC quarstions.

Books covered:

  1. Official GRE ETS books (older editions as well)
  2. Magoosh
  3. Manhattan (which was really bad for verbal)
  4. I have been thinking to solve Big book but again I have read many threads online saying it is too easy as compared to today’s GRE pattern

Please suggest what should I really solve before exam?

Thanks,
Chetana

For RC, the Big Book has plenty of challenging passages and questions. I think you will be fine to make your way through the RC there. You can also use the Analytical Reasoning sections of the Big Book for those questions that mimic the critical reasoning questions that are in the Verbal section.
