actually, you're wrong. i'm currently taking an online microbiology class WITH lab from university of new england. i thought it sounded incredibly stupid, but i'm actually really impressed with the lab software. it's set up so you've got an image of a lab, complete with bunsen burner, loops, scopes, incubators, etc. sure, it's not like actually being in a lab, but for me it's good enough.
i had to retake this class because my pre-req was over 10 years old. i work at a biotech company, so i'm in lab all day long anyway. this class was actually recommended to me by MCPHS as a great alternative for someone with my background to fulfill the pre-req.
all i have to say is don't knock it till you've tried it. i was shocked myself!
