Karen, I love it when students want to or are willing to go the extra mile. It can really vitalize their enthusiasm and interest in learning the material. I just choose not to award credit for it. My grading is set up for 100% of of the assignded work. Now, a bonus question or perhaps dropping the lowest quiz score (when there are many quizes) is probably OK if any "adjustment" is to be made, because it won't impact the final grade that much (5 points out of 1000 perhaps). My opinion, others have their own policies about this and it's up to them to decide what works and what they want to do. Barry Westling
