Marquette University Bioelectronics

I’ll be entering as a freshmen at Marquette University with the Major of Bio-electronics. This is basically electrical engineering and bio-medical engineering. I am also on a pre med track, so I have a difficult four years ahead of me. So, I was wondering if anyone had any advice? In regards to study habits, time management, or anything that would help. Any help is appreciated because I want to have a high GPA, so I can get into a really good med school.
