Exam #3 Solutions (4/14/2025)

The solutions to the problems in Exam #3 are now available at the course Moodle site.

Exam #3 Results (4/14/2025)

The average score for Exam #3 was 74.6. The average score breakdowns for the individual problems (converted to percentages) were:

• Prob. 1 - 77%
• Prob. 2 - 73%
• Prob. 3 - 63%
• Prob. 4 - 75%
• Prob. 5 - 60%

Each student's score was raised by 5 pts in acknowledgement that the exam might have been a little too challenging. The overall average score of 74.6 reflects the adjustment, but the individual problem averages above do not.
