Grading of exercises: Each exercise gives one point. Thus, you can typically achieve 3 or 4 points per exercise sheet in total, depending on the number of exercises in the sheet.
A notable exception is sheet 3, for which you could have obtained 5 points in total, since exercise 4 of sheet 3 gives two points.

Some exercises, namely exercise 0 of sheet 1 and exercise 4.2 of sheet 3, are "bonus exercises". The significance of this label will become clear in the next paragraph.
In total, if the number of points you obtained exceeds 0.5 times the total number of exercises that are not labeled as bonus exercises, you will get 0.25 grades bonus at the exam.
