Hi jaysaccharide,
To start, many Test Takers are unhappy with their initial practice scores, but you really shouldn't be. This 480 isn't too bad (the average Score on the Official GMAT hovers around 540-550 most years) and it's just a measure of your skills right now. Over the next several months, you'll work on learning the content and developing the necessary skills to improve. Raising a 480 to a 700+ will likely require at least 3 months of consistent, guided study - and you'll have to make significant improvements to how you handle BOTH the Quant and Verbal sections. Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level.
Based on everything that you have described, you would likely find it beneficial to invest in a GMAT Course of some type (either Guided Self-Study or instructor-led), so you should plan to look into the available options. 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 out 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.
If you have any additional question, then you can feel free to contact me directly.
GMAT assassins aren't born, they're made,
