Ah, DEP! I remember it well, back in 2003! What MOS?
Anyway, you can definitely fill out general education crap with eArmyU, but pretty much every lab class should be done in person. I have no doubt at all that there are quality lab classes online somewhere, but I have heard whispers of them throughout the halls here at UoP and yea, they are frowned upon. Mind you, I'm a huge proponent of community colleges and such, so don't get me wrong. The real core of our education in the health sciences is derived from know-how regarding bio and chem. It'd behoove you not to shortcut those.
To square yourself away properly, take your science classes at a brick and mortar institution (Chem, Bio, OChem, A&P, etc). I'd recommend not taking Calculus online, but I'm awful at math, and needed the hands-on office hours to figure a lot of it out. If you're a math wiz, then take it online.
Lastly, remember some things for BCT and beyond:
1. Ain't no point in looking down, ain't no discharge on the ground.
2. Tuck your shirt into your underwear - You'll thank me later.
3. HOOAH LIKE YOU MEAN IT.
