Stress

I have a test on Thursday, April 22nd in my math class. I am worried because I do not fully understand all of the concepts that are going to be on the test. I went to see my teacher this morning for extra help during her office hours, and I will go to see her again Thursday morning right before the test. I will do my best to study tonight and tomorrow in the hopes that I will be able to understand all of the information needed. This test could make or break my grade, therefore it is very important.
