Looking at your post history, you went to UCLA...hate to break it to you, but UCLA isn't ranked in the top 20...I believe they were ranked #25 in the last US News rankings. Even if UCLA was a top 20, nobody cares...you sound like a total prick every time you say that.
I went to UCLA too as an undergrad...it's tough, but isn't that tough where you need to study 10 hours a day. You can do fine if you put in a consistent study schedule. I know plenty of people at UCLA (including myself) who worked, got good grades, and still had time to party or go out with friends. I worked 30 hours a week, and I know that I partied at least every Thursday and Saturday night, and I went to almost every home football game every Saturday. Heck, I'm in med school now and I still have time to go out at least once a week....most of my class goes out Friday and Saturday nights as well...those who don't go out usually spend their time with family or what not. Not too many people are studing on Friday and Saturday night if there isn't an exam on Monday.
You're either horrible at time management, or incredibly inefficient at studying. Instead of coming on here and complaining about the "sacrfices of a pre-med", maybe you should take a look at yourself and analyze what you are doing wrong.
If you want guidance on how to be more efficient, then you should ask that.
If you just want to moan and complain, then go call your mom.
