Biomedical engineering vs biochemistry for pre med?

Planning on studying biochemistry in the fall along with computer science. I am ~curious~ about either biomedical or mechanical engineering and potentially thinking of transferring into engineering.
Would this kill my GPA for med school or… ? I am Strong in math and calculus but physics is def not my strong suit.

Engineering is a tough road for pre med. Personally I would not recommend it, your competition in engineering will be very strong and there are quite a few washout courses to get through. Med schools value GPA over all else, so if med school is your goal choose the easiest road to a high GPA.
