<p>Just breathe - I'm an MD, so I've been there and my D is a junior at another Ivy and my DH has taught high school chemistry for years - I know a little of which I speak.
First of all, the chemistry department/pre-med at Brown is just nuts, plain and simple. Freshmen, even Ivy League freshmen have no business in organic chemistry. A few true chemists, and a few people who have gone to science magnet school type places that offer very advanced science courses may be, but your average freshman - no way.
Second, there are many paths to med school, but the first and most important thing you need to decide is whether or not doctoring is for you. Take classes that interest you, anthro and cognitive science are fine, take computer science - your mom may know more than you do - take a government or sociology course or history.
Try to find a health care related internship, doctor shadowing opportunity - if Mom and dad are so set on med school, may be they can help, preferably at a hospital large enough to have psychiatry or some formal behavioral medicine, so you can get a chance to talk to people doing the care part of cognitive science. It is almost the norm now for students to take 5 or 6 years (including undergrad) before starting med school, either finishing their courses slowly, doing a post-bac after a non-science major, or working for a couple of years. You need to learn about medicine first, then either embrace it or discard it. If you learn that science and medicine is not for you (remember medicine is the application of science, it is different than "real" science), that's great, this is about exploring and demonstrating to your parents that you are making reasoned choices in a logical sequence, not just giving up after a bad semester.</p>
<p>After observing my D's experience, that of some of her friends, my own experience, and scuttlebutt from community physicians who sit on the admissions committee of a med school, I'm beginning to believe that trying to go to med school from an Ivy League college is probably a bad idea for most of the students - oh, yeah there are some real stars, and science geniuses, but there are also a lot of good potential docs who get turned off, and the weeding out is a little different than in a large public university.</p>
<p>Finally, go talk to the career services people at Brown, they may well have some advice for you on options and careers. There is a huge world out there, beyond professional schools, and professional schools may make more sense after exploring lots of options.</p>
<p>I just read your other posts - good for you. I still encourage you to take that computer science course, you might be surprised. I also encourage you to visit the Career people at Brown, the services the y provide may be invaluable, and they are there to serve you. you have a bright future, one bad semester just slows it down, it doesn't totally derail it.</p>
