That question is very individual. some students will tell you that a 480 is a very difficult bar to reach while some will say it was their starting point. If you know that is the level you need to be admitted then I would highly recommend taking a practice exam either through Princeton Review or the GMAC website to see where you stand right now. You may be pleasantly surprised to find that you meet or surpass your goal already or you may find that you need to study to improve. The good news is that a 480 is a very reasonable score to try to attain so if you are not at your goal already it should be something that studying and applying yourself should be able to fix.

Best of Luck.

Thanks for the reply. I will most definitely take a practice test to see where I am at. My main worry was the quantitative section. I am pretty sure I will need a refresher. I figured the question was going to be one of individuality.
