Hi Frisbee68,
When it comes to studying for the GMAT, there are a variety of different resources that you could use. Based on the strength of this initial CAT Score, you could potentially hit 750+ with a number of different resources, so you should start by deciding whether you would prefer the 'structure' of a formal Study Plan or not. 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 website (
https://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.
Many Business School Programs expect Applicants to have 2-5 years of noteworthy Work Experience, but not all of them do. Since you know the exact Program that you're interested in, I suggest that you speak with an Admissions Expert about your overall profile and application plans. There's a Forum full of those Experts here:
