Cornell is not grade deflated and is actually grade inflated, like the rest of the Ivy League universities. Average GPA is over 3.4. As late as a few years ago, Cornell published the median grades of each of its classes and the vast majority of classes were curved to a A- or B+ median, including most upper level science courses.
There are plenty of research opportunities on campus if you are so inclined. Cornell has an externship program that pairs you with local physicians to shadow. In addition, many premeds volunteer at Cayuga Medical Center for additional clinical experience.
The bio courses and the introductory premed classes are big (over 100 students) so you will have to work to get yourself noticed. I suggest going to office hours, which few students go to. In addition, many of the humanities classes and upper level science classes are much smaller so you should be able to develop relationships with professors then.
It’s a big school. You are going to develop your own group of premed friends with whom you’ll study with. No one goes around sabotaging lab experiments or tearing pages out of books if that’s what you are asking.
