Also this semester i had Calc 4 (Linear programming and Differential Equation), Microeconomics 2...
My course is Economics, i'm studying all the time, it's necessary and i like it, but sometimes you get a little bit tired....
And i work in the University as an assistant to a professor, 4 hours, 5 days a week and my classes are on the morning and night.
