Awww, well, don't let it discourage you. It's not like I blindly went into the NMAT not knowing what was in store. I made sure to go through the practice test, and I also studied/reviewed a little from my Kaplan MCAT book. So, I'm sure if you took (say even a week before the test) time to study a little bit at a time, you will feel better about going into the test should you have to re-take it.
But honestly, as long as you make the cut-off scores necessary, I think you'd be accepted somewhere. Don't be too down on yourself. I hope it all works out for you.
