If I scored a 590 on practice test, how much to get 630?

[dubc1982]

I'm trying to figure out how many more questions I would need to get right to boost my score from 590 to 630? I understand my score is based on the difficulty of the questions, but generally how difficult would it be to get my score up by 40 points? I feel like on the practice test that I got a 590, I didn't do as well as I should have.

On the Quant. I got the first 7 of 10 questions wrong, which should not have happened (I don't think they were terribly hard, must have just made mistakes). Overall got a 19/37.

Verbal did ok, had a tough RC passage where I think I got 4 questions in a row wrong. Overall though, I'm not too bad in Verbal. Haven't really studied much on it cause I struggle so much in Quant., but in these last few weeks before I take the real GMAT (Aug. 2nd), I'm gonna beef up my Verbal studies. Overall got a 29/41.

Assuming I'm able to comfortably handle most middle/middle-hard questions, how much better do I need to do to boost my score from 590 to 630?

As you said, it's not based on how many questions you got right. You said that you got the 7/10 of the first math questions wrong - put those 7 questions at the end of the exam rather than at the beginning (and the same for verbal), and you'd probably have hit 630.

So, really, there's no way to tell you how many more questions you need to get right. That said, improving 40 points isn't an unreasonable goal, and with another month of studying you should be able to do it.
