midsemester grades

We made a mistake when computing midsemester grades. Specifically, we used the wrong values for the programming portion of snakes. If you did substantially better (resp. worse) on the programming portion of snakes than on expression trees, then your midsemester grade will be higher (resp. lower) than the one on the HUB. If you did about the same on both assignments, your grade probably won't change. Sorry for the mistake. You can come to my office hours on Thurs if you want to see if your grade changed.
