CHANGE THE DUMB GRADEING SYSTEM

What is wrong with our school grading system. As student's colleges look at your letter grade, all colleges would agree that a ten point grading system is what makes A and B different. At Lugoff-Elgin High School we work on a seven point system. When colleges look at your grades they are looking at the letter grade believing it is on a ten point system not a seven point system making your grades look different based on a letter even though it's actually a college A. For example if I had a 91% at Lugoff - Elgin High School I would have a B, but if a college look at my grade they would say I have an A, but colleges don't know the difference. This makes grades appear different giving student less likely of a chance to get into the colleges of there dreams. I propose a ten point grading system in place of the 7 point system.
