I am 2/3 of a great teacher

I currently have 3 classes that I teach. Two geometry and one algebra II class. For the last three days I have been an aesome Geometry teacher. I know the rules. I can solve the problems, and the students have been geeting into it.

Algebra II is a differnt story. I have had a very difficult time remembering the rules, and today was the worst yet. I was up in front of class and a student asked me how to solve a problem. I felt confident in that I thought I knew how to solve this. I raised my marker and spoke aloud "To solve this, you must use cramers rule, wich states:...." I blanked. I had no clue what cramers rule is, or how the hell to use it. I moved aside and handed out a crossword. I am an aweful Algebra teacher. I decided to assign myself all of the homework from the current and next day to make sure I am on ball. I beleive I am ready for tommorow.

Well if nothing else I have 3 geometry classes in the Spring. I know I can handle that.
