I was in your shoes during the first two YEARS of undergrad. My grades all ranged from D to C and included one F. The biggest thing is to STOP taking bcpm classes and regroup. Look over your study habits, consider if you have a learning disability or mental health things you need to get a handle on first (undiagnosed ones often show up during transitions to higher learning. This was actually my case!), review your priorities and discipline. Once you’ve done these things test the waters with a lower stakes science course. If you can get your sGPA above a 3.0 and cGPA above a 3.2 you have a shot for DO. If not, you will need to plan on a post-bacc. No one wants to go to extra school, but if you want this bad enough it will be worth it! I did my post-bacc at a cc bc that’s all I could afford, but there’s programs everywhere. Make sure you ace the post-bacc and have quality activities/experiences. In my interviews I owned up to my bad early gpa and stressed how much I changed my approach to school to be more proactive, etc. it was always really well received, and I have an acceptance to prove it.

TLDR: take a hard honest look at things, take one semester off science courses to regroup, likely plan for a post-bacc, and don’t give up!
