Tests..Am I ready?

OK, so I didn't take the second  math test the day I was suppose too.  I have to wait until I am ready.  I felt that the time between the chapter started and the time to take the test was to short for the content we studied. So I have to take it Saturday.  I need a great grade considering she is taking 5 points off because it will be take late. Last test which was the first chapter (smh) I got a 67%.  Not a way to start the course.  So I have been trying to find a way to calmly find my way of getting ready for the test.
I have to take it in two days...ugh
