Ndbprr, <br /> I appreciate all the input and information. I know how to figure the percentage of a grade, and I can do it several ways. My initial question was if anyone knew how to use this particular tool. <br /> I think the purpose of these discussions is to help others and possibly increase our knowledge and friendships. I do not think it should be a forum to bash other modelers. Some people may not have the basic math skills to do certain things, and we should help them, not ba***hem. <br /> Paul
