Hi kellychen4721,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores. If you've been studying for just 1 month - and you plan to study for just 1 additional month - then there will likely be a limit to how much you could improve.
From what you describe, you're actually considering the Round 2 application deadlines (not the Round 1 deadlines) for those various Programs - and that would give you 4+ months of additional potential study time. This is all meant to say that you appear to have that necessary study time, so you should plan to take advantage of it.
Your studies so far appear to have been "book heavy." Unfortunately, that type of study approach can sometimes be problematic. Even the best books are limited in what they can teach you; they also can't force you to approach questions in a certain way and their explanations are often one-sided. As such, you might find it beneficial to invest in some new, non-book resources - such as an online GMAT Course of some type (either Guided Self-Study or instructor-led). Most GMAT Companies offer some type of free materials (practice problems, Trial Accounts, videos, etc.) that you can use to 'test out' a product before you buy it. We have a variety of those resources at our site (
www.empowergmat.com). I suggest that you take advantage of all of them then choose the one that best matches your personality, timeline and budget.
With the proper time and resources, you should be able to score a lot higher than this current 380. It's important to remember that the GMAT will always give you the score that you EARN though; you have to give yourself the necessary time - and put in the necessary efforts - to earn that higher Score.
If you have any additional questions, then you can feel free to contact me directly.
GMAT assassins aren't born, they're made,
