Hi Pretz,
Unfortunately, raising a score in the 400s/500s to a 730+ in just one month is not a realistic goal. You would likely need another 3 months (or more) of consistent, guided study to get up to that score level.
Before I can offer you the specific advice that you're looking for, it would help if you could provide a bit more information on how you've been studying and your goals:
1) What materials have you used during your studies?
2) When are you planning to apply to Business School?
3) What Schools are you planning to apply to?
Regardless of the challenges that you're facing right now during your studies, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level. To that end though, however you choose to proceed, you have to make sure that you're taking FULL-LENGTH CATs (with the Essay and IR sections) in a realistic way from now on. Skipping sections (or doing anything else that's unrealistic) will not lead to an accurate score result and you won't be properly training to handle everything that you'll face on Test Day.
GMAT assassins aren't born, they're made,
