To sum up, here are your options:
1 - Finish your degree (this is first for a reason) then either apply for OCS or get a civilian job. This option will take about 2 years.
2 - Drop out of college to enlist, wait 1-2 years before you can apply for STA-21, then, if you're accepted finish college, if you're not, you can try to finish you degree on you own time. This option if you get accepted will take 3-4 years, otherwise, closer to 8 years.
Seriously, finish the degree first. FYI, ME is a lot more versatile than NE.
