Craig Lecture MidTerm #2 Results
The MidTerm #2 Solutoin Key can be examined online.
The 113 people who took the second Astronomy 104 midterm got an average score of 37.3/50 (corresponding to a C+) with a standard deviation of 7.1. The high score was 50/50 and the low score was 20/50. For determining grades, I assumed a score of 50 was 100% on this exam.
To access your scores, enter your modified Dragon ID (MDI). Your MDI consists of the last 4 digits of your Dragon ID plus the middle initial of your name (if available). Try first with the middle initial. If your score doesn't come up, try just the last 4 digits of your Dragon ID. If it still doesn't come up, check with your lecturer.
The distribution of scores are shown in the plots below:
