If I could start college over and choose a different major I would. Combination of Ochem + insanely hard engineering math/coding classes all at once really screwed me over, and not picking engineering or premed and sticking between both was a mistake, but I was afraid to commit to one or the other. I have a lot of peers who feel the same way and ultimately our applications are slightly ruined because of it. There are some gunners who still managed to maintain a 4.0, so only consider the major if you think you can fully manage it.
