That would depend. The "end of course" exams would not mean anything if they are teaching seventh grade English to high school sophomores. Or, eighth grade math to high school seniors. Just because they complete the end of course exam doesn't mean they have been taught at their age level.
Some people don’t get the point you made. These “end of course” exams will not be standardized and will not be graded on a statewide basis. It basically takes the testing from the state and places it in the hands of individual school systems.
