How many questions should you be getting right in the OG?
Source: Beat The GMAT — GMAT Strategy |
There is no formula...I would say that it is probably more important to KNOW how to do the problems in the OG by the time you take the actual test. Naturally it would be nice to get most of them right, but it is more important to know how to do them (even if you miss the question and then learn how to do it).
The key is to have all the tools in your toolbox and be able to recognize which tool to use on which problem on test day. Hopefully when working in the OG you will be mostly applying tools that you already have "sharpened" through use and practice but if you still have to learn how to do a few questions that is no problem.
For a more direct answer to your question, if you are near to test day and you want to get above a 700 I personally would want to see 9 out of 10 questions right.

Will let you know! My test is next friday and I've just started cracking the two supplemental books open as I finished the OG. Over the last 3-4 days I've been running atleast 90% accuracy on all types/topics with (hopefully I can maintain) a 100% accuracy on critical reasoning. My target is 700+ as well and my practice tests have been 690, 700, 710, 700 over the last four. I agree that it's more important to understand how to do them versus right or wrong though. When I go back and do old problems I see the traps right away. End of day, nearly every question in there is truly not that difficult it's just a matter of "seeing" the question.
