• [Wed Oct 26 20:29 2011]

The Blackboard Grade Center for CMSC104 has been updated to include Quiz 1&2, Homework 1-6 and Classwork 1-6.

There is also a new column for your Mid-semester score. This score is the percentage of the possible points so far that you have obtained. The Mid-semester score was computed as follows:

```   2 Quizzes   = 2 x 6     = 12.000  points
6 Homeworks = 6 x 36/13 = 16.615...
4 Classwork = 6 x 14/18 =  3.111...  (18 classworks is a guess)
------------------------------------
Total possible points   = 31.72...

```

Your score in the "Total" column is added to any extra credit you received and divided by 31.72... giving you a percentage.

You can think of this score as roughly what your grade would be if the semester ended today. It should give you a pretty good indication of where you stand.

The Mid-semester score is computed off-line and will not be updated even if your scores change. (This is because Grade Center does not know how to add or divide.)

The questions submitted on paper (Questions #1 & #2) were returned in class yesterday. Note that the paper questions were scored out of 60 points, but should have equal weight as the programming questions. So, the posted scores on Blackboard are computed by:
hw2 total score = (paper score ÷ 3) + (program score)
