Remembering a (required though relatively elementary) math-heavy class, after high school, where there was an accompanying workbook to the textbook. As the ‘teacher’ of the class simply regurgitated an outline of the assigned text each day, and being a voracious reader, trouble brewed due to plowing ahead in the workbook (reducing boredom). Must-stay-with-the-class message received. Personally thought end-of-year test should be available to anyone at any time to determine comprehension. And this was in the 1970’s - the downhill slide began years ago, even thereafter soon to include the ‘revered’ SAT testing.
