A college education can be gotten online for very low cost or even for free, and one of the purposes of this blog is to discuss the various resources which are available online for that. One of the concerns that many people would have with getting a self-directed education with online resources is getting the college credit for it. Charter Oak State College offers 24 hours of college credit for passing any of the GRE subject tests, which are offered in subjects like math, biology, and English literature. I've assembled an assortment of resources for studying for the GRE subject test in chemistry, and will be doing similar articles for the other subjects.
