So, this is sort of a strange question. I'm a freshman undergrad right now taking the basic pre-med courses. But I wanted to get your input on this question...is the fact that I'm finding some of my early science classes challenging in any way a good indicator of what to expect in med school? I feel that while if I put in hard work, I can do well in my classes, but if these classes are pretty tough, does that mean that med. school eventually will just be impossibly tough? I guess I'm just looking for opinions on how to know if this is a good path to stay on. I'm definitely interested in medicine (not because of what I feel like I'm expected to do, but for its own sake), but I also want to be a competent practitioner if I ever get there. Basically, the question is, if you have to fight it all the way through undergrad, should that be telling you something about your capacity to become a doctor? I'm at a pretty competitive (top-15) college, if that makes any difference.
