As everybody else says, it's fine. An additional piece of advice - don't think about the August MCAT. The med. school application process is tough and expensive enough without the added stress and $200 of a second MCAT. Do it once, do it right.
If you're looking for study strategies, there's a forum on SDN devoted to the MCAT. Let me also say that I got a 35S, first time, with only an $80 Kaplan book, a $20 Kaplan practice test book, and 3 practice tests from the AAMC. Oh, and I borrowed a few "quick reference" sheets from a housemate who had already taken the MCAT. I studied hard for 2 months, then kept reviewing for a third before my MCAT. I strongly believe that MCAT preparation courses (which cost quite a bit of money) aren't necessary. I also have a GPA that's nothing to write home about, so don't think I'm one of those academic over-achievers. The MCAT is a standardized exam. The questions are the exact same thing year after year, and therefore, fully predictable. There is nothing to be afraid of. Best of luck.
