3.59 GPA, 29.8 MCAT is your average accepted student, I think.
I had a friend who had a 3.85 GPA and a 27 MCAT and good activities and I think he got into 3 schools (including a top 50) and waitlisted at 2 (both in top 50). (Applied to around 15 schools). The AMCAS application has an option when you are filling out your information to check if you are taking the August MCAT. If you already submitted AMCAS, I would recommend notifying the schools in writing to make sure they don’t discard your application before your August scores come in. If you have not submitted AMCAS, you should try to get that together as quickly (but with care, of course) as you can because applying earlier will help your chances.
