Here are some of my thoughts considering I was in your shoes...
(Took mcat August 9, submitted mid-August, verified Oct 8. Deadline for primary Oct. 15.)
-Only get one chance to make first impression and if it doesn't work out, they'll expect more from you the following cycle.
-Less interview slots meant I had to be more unique or superstar to garner interview invite.
-I wasted money on application fees.
-Applying to a single school, which you won't even know you're competitive for until after you submit and get mcat back is setting yourself up for failure.
-even if you don't submit secondary this year, you are considered reapplicant and they will ask how you improved your app since last cycle (extra work next year)
10/10 would definitely have waited a year to apply. Excited for this cycle cuz I'm on top of everything. I would suggest getting started on AMCAS during your free time for next year though. Also if you're not ready for MCAT, then postpone. Trust me.
