30 points imporvement IS IT REALISTIC? 640- 670 or more

Thanks..

Yes, I have exhausted official questions for the Q section,. The thibng is, I am still strugling with the Coordinate plane/ angles and Geometry.. if the questions are just above a really basic level, I get confused.

For Q section I am using the GC exams, some questions in there are really good.
I will focus on the verbal forum.

Thanks both for your reply , much appreciated

Sorry to join the conversation a little bit late, but I definitely think that a 30-point improvement is a completely reasonable goal, especially since you've already identified some clear areas of weakness. It's actually a really good thing that you're bad at geometry, since that's a completely fixable issue.

This might sound obvious, but make sure that you get TONS of CR and RC practice from official sources. The strategy guides can be really useful, but most test-takers are held back--at least to some degree--by a lack of precision in their reading on CR and RC, and the only way to battle that is to practice like crazy. The more nasty, difficult CR and RC questions you see, the better you'll get at fighting your way through the language. You might consider using the LSAT for CR and RC if you've already exhausted all of the official GMAT materials.

A 34 is a solid score and I have a feeling that your SC is already really strong, but don't let it atrophy during the next few weeks. If there are any official questions that you haven't already used (in the verbal guide or the GMATPrep Question Pack, maybe?), then be sure to hit them hard this time around. You're probably already working on SC, but I thought I should mention it, just in case.

I think your goal is perfectly realistic, and you sound awesomely dedicated to achieving it. Good luck with everything, and please let us know how it goes!
