# Exercise classes

Lectures and exercise are on Tuesdays and Wednesdays.
The plan is to have about every 2nd week on Wednesdays an exercises class.
You mark in the online-kreuze system those homework problems you did.
(Deadline Tuesday 09.55), you hand in your written home work beginning of the Tuesday lecture.
I will look at your homework write some comments, (but not fully graded), and will
ask you to present the homework on the board.
(I hopoe this improves the quality of solutions on the board...)
The grade of the exercises depends on the quality of the homework and presentation,
and the number of crosses you did.
