Andrea, Sure, that's fine. I think having a bonus question on an exam that allows a student to demonstrate knowledge beyond what the instructor asks for is not a bad idea and, in fact, I routinely do that. I think a bonus question, available to all students is a bit different from extra credit. Some may say it's just semantics. But I think it's different. What you and I are suggesting adds to the assessment of learning, while EC tends to just give away points with little merit or contribution to demonstrated learning. I will also drop the lowest quiz score (I give a lot of daily 10-point quizzes. Both actions I've described help assess student performance but don't really alter a grade that much. Barry Westling
