Let me see if I can help.
Bio and Chemistry can be taken together since Chem prereq is college algebra which I'm sure you have.
Micro and A&P1 I think should be fine together, just consider every science course has a lecture and lab portion. I did mine through DCCCD b/c it's cheaper (not together though and def not working full time), and no problems... but if you know what you want and you have the luxury of a set schedule, you can manage your study time no problem I think.
In Spring I'd recommend Intro to Nursing, Upper Division elective (If it's required for you. Some previous upper division courses have been substituted for the elective for friends of mine, despite what the website says so check with your advisor at the College of Nursing) and take A&P2. I did a science and those 2 UTA courses and it's manageable. They're online, and one of those is a super short class, 5 weeks I think. Summer, take Patho and Pharm. Yes, it's heavy. But that is exactly what the program is like. Distant learning, student driven study. 1 exam every week just about, plus assignments and clinicals in between. So if you can make it out of those two.. you'll get a feel for the program. Your 3 sciences will be one of your ranking GPAs so As are highly recommended. That will bump your overall too. UTA is infamous for wanting technical writing and I don't believe that's changed so look into that if it wasn't required for you BBA. Also, THR takes up to 10 of the students with previous bachelor and offer a scholarship
. Fort Worth isn't super close, but it might be worth considering. I think it's 100% reimbursement, but they want a contract. Don't quote me on that though. Looks like you're in for a heavy next 2 years, but it's doable. Just do it. You won't regret it. Good luck!
