I once met a teacher who made fun of me in front of everyone for not being able to say my number on the list. Good that he only taught me a year. The ones I have now are mostly fine, one teacher once allowed me to resign of the presentation if I don’t feel up to it. I download this app a long time ago, but honestly I forgot about it. I will try to use it in next week. Now I have a weekend and at least two days without stress :)
