I livein Texas. Here our grading system is hard. In Texas 90-100 is an A. Here 80-89 is a B. In Texas 75-79 is a C. LAst 70-74 is a D> 69 and everything under is an F. I hear it's not like that in California. I hear you could have a 6- there and make a D. We've got Science and Technology in Texas but I don't think we should have such a high grading standard.
