be careful
I went to spartan for some of my training. I will tell you if I had it to do all over again, I would cut ties and run. These big schools are big for a reason. I got through my commercial in less time and money than most and still would have been better off elsewhere.
I can agree with Wx about riverside flight center. They are great and fair. They don't ask for money up front and can get you where you want to go.
Good luck and if you want any advice on the Tulsa aviation scene, send me a line.
