What are you talking about? An 82% passing rate is ideal. It means you are doing a great job and also probably allowing enough students to take the class. A 100% passing rate would indicate you should probably be increasing enrollment in the class.

This was my 7th group of Calc AB and by far my lowest passing rate (82%). I'm kind of at a loss, but it is what it is. I thought that I'd prepared them as well as I had before.
