Good luck at NETTTS. If you aren't totally comitted yet and you could hang out in Deleware while going to school. They have a real cheap community college down there. The cost of the motel and the school would be cheaper than $3500 I believe? I'm not totally sure, but it looks like the CDL class is $1000.
http://www.dtcc.edu/ you have to look around the website. It is the commercial transportation class. One class is $500 and one is $1000. I'm not sure what the difference is.
