I did pre-medicine and engineering and I couldn't stand how cutthroat the students were in my bio/chem/ochem classes. The pre-meds are a bunch of conniving bastards with no lives, if you ask me. I'm only half kidding, by the way. It really depends what you're looking for in life. If you truly want to be a doctor, then suck it up and just grind it out. Based on my experience, I would say that you're going to hate your classmates for 4 years, semi-hate them throughout medical school and come out with a rewarding career in medicine, assuming you pass boards and get your residency done. When people say it's hard work, they're not mincing words. I'm literally not joking about having no life. My friend at UCSF Medical School told me she studied upwards of 8 hours per day, on top of having leadership positions in clubs, securing a research position after her freshman year, having 10 published papers on PubMed and attending all lectures. That worked out to about 2-4 hours of sleep for her a night for four years, a 4.0 undergraduate GPA in Molecular Biology, and a lot of hating life. In the process, she also became a sociopath and I'm terrified that she's going to be a doctor - my only solace is that as long as I have a say in it, she won't be mine. Overall, my experience with pre-meds has not been favorable. A couple of my more prominent memories of organic chemistry involve taking my friend to the hospital because he had a nervous breakdown, not being surprised that somebody ripped out key chapters of the ochem books on library reserve, and having heard multiple classmates tell me that they've had their books stolen from their dorm rooms/apartments/backpacks during finals week. I highly recommend investing in a good set of locks, not sharing your room with anyone, and never taking your eyes off your stuff. My friend who had the emotional breakdown developed paranoid delusions that someone was going to break into his room while he was gone and steal his ochem/bio/chem books. Another friend left her study area in the library while studying with "friends" to pee and came back to discover that her ochem book was missing and that her "friends" didnt see anyone take the book. She later found that the book had been returned to her with pages missing (presumably so she couldn't even sell her book back to the bookstore after the quarter ended)... after everyone had taken the final exam. On the bright side, you will make friends. 90% of these friends will copy your homework, never allow you to see theirs, and lie to you about when midterms are or when/where things are due. Don't drop your guard. Seriously. From glossing over your other post about your parents, it sounds like you will probably end up rebelling against the parentals and partying like hell in college. You don't want to be in pre-med for that, it'll wreck your gpa and screw you out of medical school. Bottom line of my rant is that you have two options: have no life in college, work your ass off and not sleep, or enjoy your undergraduate experience and maybe decide to take pre-med courses after you've worked the party out of your system. I've had 90% of my friends either burn out doing pre-med or wreck their GPAs to the point that even grad schools won't take them. The scary thing is is that you'll convince yourself that this will never happen to you - you'll never burn out. After all, you did well in high school, right? Wrong, bro. Everyone thinks they're the shit when they're 18. Only a few people actually are. Better to not chance it and find out you aren't the hard way.
