How can I raise my score by 100+ points in 1 month?

HI prettypeachheart,

Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so it's likely that you just have not put in enough time and effort yet. You'll also likely have to take CATs more frequently than you did before (1 FULL CAT per week - give or take - should be part of your plan). There are other factors to consider though, including how you took your CATs.

When you took your CATs:
1) Did you take the ENTIRE CAT (including the Essay and IR sections)?
2) Did you take them at home?
3) Did you take them at the same time of day as your Official GMAT?
4) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?

With a V27, you lost points on all 3 major Verbal categories (SC, RC and CR), so even though you've self-identified RC as a 'weak area', you have to continue to work on ALL Verbal areas to significantly raise your score. It would also be easier for you to score 700+ if you picked up a few extra points in the Quant section.

At this point, the 100+ points that you're looking for will require that you focus on Tactics and the 'precision' in your work (note-taking, thoroughness, etc.). Thankfully, the GMAT is a predictable, standardized Test, so you CAN train to score at a higher level.

GMAT assassins aren't born, they're made,
