Was Thinking About Majoring in Biomedical Engineering Before Going to Dental School, But...

Okay, so I'm 17 years old and I just finished my first semester at The University of Arizona. My current major is undecided engineering. I know that it might be a little late, but after some more research, I realized that it's very challenging to get admitted to a dental school after majoring in Biomed, due to the difficulty of the courses that might lower your GPA. So, I'm trying to consider other options that are more helpful and in the field that I'm trying to pursue. Any suggestions?
