Strike week for teachers

We are very busy as we dont have teachers because they are in strike.
We are doing a challenge, it  has 4 differenet challenges in it, and every menber has to do his challenge.

Next week we have exam from communication challenge, and personaly I am nervous.

I have many questions and I dont know what to do.

I hope to learn a bit with my team mates.
