C23 Wireless microphone

The test began and it was not very simple, I did the one's I could and I at least wrote something on the questions I did not know the answers to.

I do not like to leave my papers blank, I saw a few people whispering to their selves probably telling answers and papers were flying around.

luckily the teacher was deep in a deep sleep, one paper landed next to me and I knew answers were in it
