Just about all traditional colleges (including community colleges) and universities offer some online classes. It’s best to steer clear of those online, for-profit schools (though may have ‘brick and mortar’ campuses and may be ‘accredited’) such as penn foster, excelsior, devry, university of phoenix, capella, ashworth, high tech, argosy, sanford brown, everest, remington, ITT tech, kaplan, ashwood, walden, ashford, colorado tech, keiser and others as they are merely out to ‘make a profit’ (and course credits may NOT transfer to other schools): http://www.ripoffreport.com and can search.

If you absolutely must study online, the following non-profit schools are among the best and cheapest:

Athabasca U
Excelsior College
Western Governors U

You should contact the university authority regarding tuition fee, because some universities provides financial aid to students.
