Many threads about taking the pre-med required courses have been posted, and the general consensus has been that it doesn't matter if they are taken at one's home undergraduate institution or not. However the ADCOM strongly disagrees and says "it is very bad!!!". Anyone's thoughts about this controversy?
After reading multiple threads on SDN as well as other forums, it seems that there is still no clear consensus about this issue. Some are strongly opposed to taking pre-med required courses away from the home university, while others would argue that it doesn't matter. In my opinion, doing this isn't always necessarily a bad thing; but you should be cautious. I don't think that having one or two pre-med summer courses at a different university instantly raises a red flag on your application, unless it obviously appears that you're intentionally avoiding taking the course during the year because it might be harder to get a good grade. By that, I mean, if you took O-Chem 1 (for example) and dropped it with a "W" and instead took it over the summer somewhere else, it might look like you're chickening out. Another example would be someone who has a relatively low BCPM GPA. In this case, taking pre-med courses away from the university might look like you're "cherry-picking" for easier classes to get A's in. Those types of situations might draw some suspicion, but still, it's not going to completely sink your application.
Also, there is a difference between taking the pre-med required course at a CC as opposed to a 4-year university that just happens to not be your home institution. I think the former is often frowned upon, while the latter is okay as long as you do it sparingly. I think if you're taking summer courses to accelerate your course plan, or just don't have anything more productive to do (like research, summer programs, job, etc.) for a particular summer, it's all right. I'm currently taking Calc-based Physics (actually much more intensive than the trig-based "pre-med" Physics offered at my school) at a state school this summer, partially because I didn't have anything better to do, but also because it would free up some space in my junior year schedule. With the two Physics courses out of the way, I would be able to take more upper-division science courses that I am really interested in, but would otherwise not have time to take. I could have taken the Physics at my home university over the summer, but doing it at this particular state school was so much more convenient (closer to home), not to mention MUCH cheaper (which is probably the deal-breaker for me).
Hopefully we can find more interviews or articles from other Adcoms regarding this issue for a second opinion. I've also read a few pre-med advising FAQs from various universities, and they all seem to agree that taking summer courses elsewhere is permitted and won't harm your application as long as you don't do it too often. I'm taking the responses in this interview with a grain of salt (partially because some of the answers weren't that in-depth IMO). Personally, I don't think this should be too much of a problem, as long as it's done reasonably. And by reasonable, you should be able to determine this yourself. If you're scheming in the back of your mind to get a better grade by taking it at an "easier" school, then it's probably not a good idea to take it because it'll show. Be honest to yourself, and you'll be fine. Don't worry about it too much. I also don't think that they'll scrutinize over every single course you've taken and where you've taken it, and repeat for each and every other applicant. At least not until they've narrowed down the field quite a bit. But by then, you'll probably be able to explain yourself at an interview if it ever comes up. Admissions officers can't (and don't) really judge you on each of your classes, because the difficulty level can vary greatly among every university. The only proof that you've properly learned the material is your MCAT score. So if you do well and ace that part on the MCAT, that should dispel any doubts.
