How grades are assigned?

Completely HWs based.

Homework regulations

HW has to be typed in what ever editor you like.
If you were asked to produce any output -- it has to be copied in the HW text.
If you were asked to plot something, this plot has to be printed.
Essentially, it is recommended to type all HW together with plots and cut-and-paste outputs.
