I'm planning to take the GMAT in late August and took the GMAT Prep practice exam today, April 16. I scored a 580 on the practice (33 Quant and 37 Verbal) and plan to follow a plan I found on this site that suggests two hours of studying a night plus five hours on the weekend.

I haven't taken a math class since high school (journalism major looking to change gears), but I've always been good at math... just need to refresh my memory bank on some formulas and basic rules. I did zero studying for the diagnostic test I took.

At any rate, I'm trying to gauge how much I can expect to improve my score. Is a 700 unrealistic?

Appreciate the help.
