Usually anything over 18 you have to get permission from your academic counselor.

LOL yeah same. 21 credit hours I would probably just say fuck it and kill myself. My brain would fry itself

do p.e and music count

I took organic 2, physics, genetics, and precalc this semester. Had to medically withdraw though.

There's always next semester. You seem pretty smart though, so good luck.

u can take physics and precalc at the same time? had to do calc 2 before physics here

I was only doing algebra based physics. My masters is fine with calc based or algebra based, so I figured why not take the easier one to focus more on my undergrad degree of bio.

Honestly, take your time, do what you need to do to learn everything you need to learn. For med school, just stay above a 3.5 GPA and you'll be competitive as long as you do well on your MCAT. IMO stress studying for your MCAT more than your classes, I mean obviously a large chunk of it will overlap without a doubt, but emphasize the MCAT more as that's what medical schools look at more.

taking 4 science courses at a time = suicide.

I've taken 4, it's tough, but it's not suicide. 5 is a different story though, I wouldn't advocate it lol.

Anything more than 1 science class is suicide..when you start mixing letters with numbers my brain shuts off. I can't even imagine the amount of stress is be under
