There isn't going to be an exact answer for this, since your score doesn't solely depend on the number right and wrong. Your score also varies based on the difficulty of the questions you get right, at what point in the test you get questions wrong, etc.

That said, scoring a 50 on quant is very tough! My guess is that you could only get a few - maybe 2 to 4 more difficult questions? - wrong and still be in this range.

Good luck!

Thanks Jim,

Actually I completed OG Quant Review and half of PS questions from OG 11. Till now my hit ratio is somewhat varying between 80% to 95% in different sets. I will complete OG by coming week. Till now most of the mistakes were due to carelessness and except 3-5 questions got wrong due to concept.

So, what I am not to figure out is that whether I can score more than 50 or not in GMAT (if I take care of my carelessness attitude). Timing is not a problem for me in Qunat and I am pretty fast in DS as compare to PS (for most of the question I didn't even need to pick the pen).

After OG 11, I am planning to go for Kaplan 800. As Quant is my strongest part for GMAT, so I don't want to lose any score in this section. However, I am trying to gain strength in Verbal section.

Any suggestion to make Quant as 100% error free?

Take one of the gmatprep tests from mba.com.

Do just the math section if you'd like to save time.

Then you'll be able to see what you'll likely get, what you should focus more on, etc

out of the 37 questions you can miss somewhere around ~8-10 (depending on difficulty level of the questions) and still get a 50.
There is no magic hit rate % on the OG that will point to a certain score.
