So as the next application is slowly approaching, I'm becoming more nervous about my GPA calculations. Do y'all have a good system/formula I could use to calculate my GPA (pre-req/overall) based on PTCAs standards? I wanted to get a good idea before I started the application cycle. I've retaken some courses along the process and I'm not sure how that will make a difference. Also tried searching for a thread of similar inquiries, but could'nt really narrow it down. Thanks!
