One of the other considerations is that there are, for instance, different Physics I classes at many colleges. Physics I, and then Physics I for Engineers / Physics Students. If one takes the normal Physics I class at a community college and then enters into an Engineering program, that normal Physics class might not transfer to the College of Engineering. I've seen math classes and Chem. classes in similar situations.
I'd just encourage everyone make absolutely no assumptions, consider each college and each class on an individual basis and do your homework.
