dental school vs engineering

I am struggling to decide between University of Pittsburgh and Georgia Tech. I was accepted into the guaranteed acceptance for dental school at Pitt but I am worried about the GPA requirement I have to maintain. I have to maintain a 3.7 in bio, chem, and math. I am worried about organic chem most of all since I did not have a good chem background at my school. I also wanted to do bioengineering at pitt as my major for undergrad but I am scared about pursing that and keeping up my gpa. Should I switch to a bio major if that is easier?At gt I’m worried about the overall stress levels at the school. I am deciding between industrial or biemedical engineering. Both are great schools so it’s a tough decision. If anyone has any advice or tips I would greatly appreciate it. Thanks!
