Student help

I'm in my last year of school and I went through a tough patch last semester. I didn't do as well A I have been doing. I have a 3.8 GPA overall. This semester my GPA was 2.4, I have to have a 2.5 for my scholarship. In order for me to get back on it. I have to take two classes and pay out of pocket but I don't have $1200 laying around and neither do my parents. Idk what to do. I applied for a loan but didn't get approved. I have to have $660 by July.
