Hi,
I did the Diagnostic Test at the beginning of The Official Guide For Gmat Review (12th edition) and scored above average in all the sections apart from one where I scored excellent. Today I did the first practice exam of the GMATPrep and got a 650. I have not studied for the GMAT at all yet.
I am a native english speaker, and my maths skills are probably somewhat above average. What is a reasonable target for the GMAT if I put quite a lot of effort into it?
Background info: the master's program that I'm considering requires a minimum of 630, which I assume means that to seriously consider an applicant he must have ~700.
