Learning Log

The class that Im struggling the most is Calculus because its very difficult to get into the fundemnetal of the math and since I dont study very much I have a C in the class. But as my senior year is about to end and progress report is due and AP calculus exam is coming around the corner; I realize that I have to step it up and start forcusing. In Calculus I learn that there on twenty basic integrals nad including the U-substitution.
