I scored 510 without using the OG, now I have it - can really boost my score? Whats a reasonable estimate for the increase? , and should I still use my other kaplan
books, and princetons, or just their practice gmats on their respective cd's?
Any feedback would be greatly appreciated. I guess i just want some reassurance that I'm not wasting my time. I plan on taking the gmat again in about 4 - 5 weeks.
