Alright check it out. 90% of your classmates will be either married or in a relationship they've had going for 8 years. Most female med students aren't gorgeous and have rather low self esteem, meaning that most are hanging on to whatever guy they've managed to get in their pre-medschool lives. They'll hang onto this guy relentlessly, even if he IS an automechanic or the cashier at Shaw's, because they're comfortable with him and for fear of ending up alone.
The other 10% will be either nothing you'd be interested in or that awful, snobby, I'm-from-a-rich-family and I'm-too-good-for-everyone type. These women are flying high on the pretentiousness they were taught as children, and will declare themselves too good for anybody but a venture capitalist from Harvard business school with 3 ponies in the stable and rock-hard abs. Most of these latter type aren't too pretty but act as if they are, and are altogether just as cocky.
MY ADVICE: GO FOR A LOCAL GIRL WHO ISN'T IN MEDICAL SCHOOL. You get a lot more bang for your buck. For the same effort you'll get someone more attractive, requiring less maintenance, and who will likely NOT have any delusions about being as intelligent as you, and will thereby not argue with you all the damned time.
