Craig Lecture Final Exam Results

The final exam solutions are not available online. They can be obtained by contacting your professor.

The 108 people who took the Astronomy 104 final exam got an average score of 72.3/100 (corresponding to a C+) with a standard deviation of 12.6. The high score was 96/100 and the low score was 39/100. For determining exam grades, I assumed a score of 96 was 100% on this exam. However, I used the raw percentage in comparing to previous midterms.

NOTE: Multiple Choice problem number 41 was dropped from the Final Exam as being unclear. Everyone got a free point.

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.

Enter your MDI:
