My daughter took her science classes online at SUNY Rockland County, a community college in New York State. If you're lucky enough to have New York residency, it's quite inexpensive. She found the classes to be very easy, not terribly surprising for intro courses at a community college. But the lack of rigor didn't pose any problems during her grad school experience, since intro bio and chem were pretty much irrelevant to her courses. (To be honest, fulfilling those ASHA requirements, while unavoidable, was a waste of time and money.) If New York state school prices are acceptable for you, SUNY has a website that identifies all the online classes available at all the many SUNY branches. Lots of possibilities.
