- you must miss the lab for a valid reason.
- and you need to provide evidence for this reason (doctor's note if you were sick, Dean's excuse if you are planning to miss a lab in order to participate in a valid event).
If the reason for your absence is such that:
- you are not sure whether the reason for your absence is regarded as valid enough to warrant a make-up lab, or/and
- you are not sure what piece of evidence you are supposed to give:
then ask Roger Haar, haar
If you know in advance that you are going to miss a lab, let me know by email, as well as Roger Haar.
Give said evidence to me during our lab session, as soon as you have it.
The make-up lab does not take place during a different day on the same week you missed the lab, and it is not about the same material, either. It is an entirely different lab, which takes place at the end of the semester, usually the week after the lab final.
Although the work you will do during lab-time is the same, the type of assignment and the number of points that the make-up lab is worth varies, depending on whether the lab you missed was a for-worksheet-lab or a for-lab-report lab.
Also, note that only one missed lab may be made-up, i.e. the make-up lab cannot count for more than one lab.
