Final Exam

I've just finished what I hope will be my final exam at uni. This one was for GIS and I must say that I'm not really confident with how I did. It was one of those exams where we had to write down as much as we could remember. Unfortunately, as soon as I walked in there, as is the usual case, everything automatically left my head. Everything about the shape of the earth, coordinate systems, vector and raster data models, all of it was just gone. So I sat there for an hour and a half trying to remember and writing down what I could. I left with about half an hour to go. If I pass then that will most likely be my last exam of my uni career. I really hope it is and I really hope I pass. Fingers crossed!!!
