Can I use stickers to cover incorrect answers?

This is currently not advised, although we are researching the possibilities. The scanner at Canon may produce errors, which will lead to extra costs for you for the extra time for manual labour to fix the error.
If you use stickers, please take into account the following:

1. Stickers should not overlap with other stickers
2. Stickers should be attached very tight
3. Stickers should be attached very smoothly, without wrinkles
4. Use thin stickers

We advise you to always include extra writing space at the end of your assignment by adding a question without content or points, e.g. 5a and 5b.
Instruct students to refer to the spare question numbers at the question they were supposed to answer.
