The note-takin support is a paid position of trust for which a little financial compensation can be obtained. You share your own notes to others shares.
There are no rules and guidelines about how your notes should look or how they should be written. The hope is that the notes are clear, transparent and easy to follow. It is important to include information provided by the lecturer that is not in the powerpoints. The assignment may include explaining the notes to the person receiving them, if necessary.
The assignment extends as long as you agree with your classmate and can be interrupted by both parties at any time during your studies.
You as an note taker have no responsibility for the student's studies or study results, it is the student's own responsibility to make the lecture notes into useful study material.
It is the post-work, i.e. the processing of the notes before you send them away, for which you are paid, not the writing itself. The fee for note-taking support corresponds to an hourly wage of SEK 105 and for 2 hours of work/week, regardless of the number of lectures.
