Langston University offers a BSN from their campus in Tulsa. They're part of the OSU campus just north of downtown Tulsa. I think that if you take highway 75 from Bixby, it won't be more than a half hour's drive to Langston.
The only bad part is that they had 300 people apply for 25 spots. My early college years are holding me back right now, despite the fact that I graduated from TU with a 3.8 GPA in speech-language pathology.
If I was a freshmen/sophomore again, I'd really would have appreciated it if someone had told me how early college might affect your chances of getting into a program you'd really like to be in down the line.
I started off at a Christian liberal arts college located in Arkansas about 90 miles on the Oklahoma/Arkansas border. I messed up and no one cared to tell me about what that could do to me later on. I honestly believed that they were more interested in getting your money and preparing women for the M.R.S. degree, which I didn't get until 3.5 months ago! I went to that school in the 80's!
Anyhow, I'm rambling here. Sorry. But Langston is good, and Tulsa Community College is good for the prices.
Good luck to you!
