Each of the two questions were worth 5 points. Overall you guys did well - there were quite a few perfect scores, which is great. You're grader did make a few comments, which are as follows. Most of the students who knew what a curl / div was did pretty well on Q1. Points were taken off for shortcuts and lack of explanation. On the second question it was pretty much based on whether or not they knew how to simplify the integration. Those who knew it pretty much got full points, others tried to hack their way through the problem. I did give some partial credit, proportionate to how far they got.
