Hello People... I was just going through the last 50 questions of Data Sufficiency in OG and was very disappointed with my performance.
Is the real GMAT going to be tougher than this?
How should I prepare then.... there is not much quality material available in the market for preparation
It depends on the score you are targeting, but based on overwhelming feedback, OG is easier than the real thing. However, since the questions in the OG are arranged by difficulty, the last 50 are actually quite close to the GMAT. See this post for details: 640-to-710-in-1-month-75420.html#p593039
Two suggestions: you can look into the Manhattan GMAT series
- they have some good Math books to patch holes or Jeff Sackman
's GMAT Math Bible (said to be good for hard prep) but it is $50
If it is hard practice questions you are looking for, you can check out GMAT Club Tests
- 2 are free and all are free if you have 200 posts.
