I went to a top tier "cutthroat competitive" university... I'm sure there were those types of ppl at my school but I never really encountered one.
I've had friends who have done crazy crazy awesome things internationally and went to Harvard Med.... they're not like that... nor are the ppl who went to University of Your State Medical School.
However, there were those weird ppl in class that would suck up to the professor, buy every book the prof wrote, and would read those books on the side to discuss something with the prof during office hours.... I knew to stay away from those types.
Med school admissions is a mind game, you need to know how to play with the ppl you are applying with sometimes cuz you have to keept your sanity first.
Most ppl I was friends with who are applying around the same time were very open about mcats, gpas, surprisingly everything up to accepts and rejects. Maybe they just trust me too much? i dunno, but I've rarely encountered what you did Rama Kandra... stay away from that girl, she prolly feels inferior and using a defense mechanism, but don't let her bring you down too!!
