text: on line classes? i got my ba in liberal arts, and i am thinking to get into health care field, so i need to take some science classes, such as chemistry, biology, physiology and anatomy. does anyone out there know any of these classes are offered online from an accredited university? i had checked on these with two university's.  both said that you have to do in class work to learn quite a bit of it and that unfortunately cannot be done safely on line.
