Hi Gagan,
To start, essentially all of the OG questions from the last several years of OG books are still relevant to the GMAT today - so if you are interested in some additional practice, then working through some Verbal prompts from any recent copy of the OG (even going back to the OG13) would be fine. Of course, it's important to define HOW you're working through that material (re: what Tactics are you using? How do you organize your notes? When you get a question wrong, do you understand WHY you got it wrong - and can you use that knowledge to avoid making similar mistakes on other questions? etc.).
A little over a week ago, we discussed a recent CAT that you took and your ongoing studies (at the below link):
https://gmatclub.com/forum/related-to-m ... 61969.htmlIf your Score Goal is in the low-700s, then you likely have the necessary knowledge to earn that type of result right now - and the differences between scoring in the high-600s and low-700s will be about how rigorous you are about your note-taking and strategic thinking.
1) When are you planning to take your next Official GMAT?
2) For your next attempt, are you planning to take the At-home GMAT or are you planning to take your GMAT at a Test Facility?
3) Going forward, how many hours do you think you can consistently study each week?
