Have you taken an online course before? I just remember my A&P I and II courses were in person and they were hard enough and very time consuming. I am taking 2 online courses now and they are easy (subject/course wise) but they are SO much more time consuming than when I was taking A&P...I feel like I am drowning sometimes in busy work.
Anyway, you may know all of that already but I know I could never imagine having to do A&P online...I would much rather have a in person instructor. However, I don't know your situation and I am not trying to discourage you but I just know because I have had experience with online classes and classroom setting instruction. With A&P there is a lot of memorization but the physiology part you have to comprehend and can be difficult so it is good to be able to have a instructor to ask questions to in class. Just my advice and you can take it for what it is worth ;-)
