My first thought was to bump him, but then I read that he had an 87 until the extra work, leading me to say not to bump him. If he had an 89 before the extra work, then yes. Do you believe that he has tried his best every day? Sometimes, all A kids can feel like it is ok to slack off because they can either (1) get extra work, or (2) they will be close enough for a bump. Sometimes, getting their first B can be a wake up call that he might not be putting in all the effort to earn an A.
