My students, I need to say something about your first lab grade, and I do so hesitantly because I do not want to encourage you to waste time grubbing for points. On the other hand, I do not want you to be penalized unfairly. Usually, your lab grade reflects fairly your performance on the lab. We run a large number of test cases, and give you points for those that give the right answer. Your lab grade is based on how many test cases worked and how many failed. Unfortunately, sometimes a student makes one silly error that is in the wrong place so it ends up giving the wrong answer for too many test cases even though everything else is working correctly. I don't use the word "silly" in a perjorative sense -- for the cases I am talking about, the student himself/herself will willingly call the mistake silly. So, what to do. I don't want to unfairly penalize you, and at the same time I do not want to encourage you to waste your time. My answer is simple. If you honestly believe that your low grade was due to some silly error, then send email to Stephen Pruett with a simple explanation of the error and how you would fix it. He will get back to you on what to do next. If your low grade was due to more than just a silly error, then it was probably the correct grade you earned, and you are better advised to put it behind you and concentrate on the second lab and the rest of the course. The fact is one low lab grade (especially the first lab) is not going to kill your chances of an A in the course. In fact, I have been known to ignore the first few grades in the course if you demonstrate mastery from that point on. Good luck getting the problem set in on Wednesday and the second lab in next Sunday night. Yale Patt
