Exams week at college

Well, this is going to be a very busy week. I study IT at college, and this week I have to take tests every day - except wednesday . These are not the finals exams, but they are the most important, because they worth half of all my  grade. The other half of grade doesn't have to be a test - it can be from homework or something else.
I don't know if you can understand what I was trying to say , but if not , please tell me and I'll try to make it better. Thank you for reading !
