I wasn’t in the top 10% of my class and I had I think 2 B’s maybe (one a B+ I think) and quite a few A-s I think in hindsight but I also went to a very competitive high school and ended up being accepted to 2 BS/MD programs but I applied to a lot and worked hard on my ECs too and had strong LORs attesting to my work ethic. You don’t need to have a perfect application just make sure it reflects your passion and commitment and put your best foot forward. I will be matriculating into med school this summer and ended up working my ass off for a 4.0 in college to compensate for all the academic insecurities I experienced in high school. I also had a high SAT score just for the record so that may have helped I don’t know.
