You're doing this^^^^^^
And you think you'll have time for both this:
Yeah. Good luck.
Best plan? Find a faithful girlfriend who doesn't mind the long long hours that you'll be studying and working on school work. That way you can focus on your studies, but still have a ready "outlet" when you do have a spare hour or two.
I speak from having spent the time getting a BSME. Although your situation might be a little different, if you get some of the pre-reqs out of the way at the CC beforehand. In that case, live on campus that first year, have your fun, and make sure by the end of the year that you've found the girlfriend I mentioned above, because after that, its going to get busy.
