More problems and stress

In today's class we have been correcting all the mistakes we have been doing in this term. When I saw all the messages by the teacher in order to change a lot of things  I was so stressed, I have to do works like for 10 hours and I am on exams, this is getting really hard. Today I was just thinking in all the work I have to do, I'm going to be working a lot these two following weeks.

Another part that made me think about something was when the teacher told us of because of arriving late from another class. I think that if that would happen every day,  I would understand it but, actually, it was first time we arrived late and there is no need to get angry for that. I can understand anyway that she wasn't happy with us. It is always a bad thing to arrive late anywhere.
