The school is issuing certificates attesting that students have attended courses.
The rule is “you print, we sign”.

So:
1. download the certificate (.doc)
2. remove the courses you didn’t attend, and print it out.
3. deposit it at the entry desk until Wednesday of week 2 (August, 4th), 6pm.
4. collect the signed item from Thursday week 2 on.

BTW: If you can’t print onsite: just create a pdf. That will generally do.
