EMA 303 teaches mechanics of materials, covering stress, strain, beam bending, torsion, and column analysis for civil engineers.
Historical reviews of Sonny Nimityongskul, Wendy Crone: Workload expectations vary significantly. Some reviewers find homework challenging but worthwhile, while others report a ridiculous amount of homework that does not help with test preparation or learning.

Historical reviews of Andrew Mikkelson, Jennifer Detlor: Students describe EMA 303 as a very difficult course. However, instructors like Andrew Mikkelson and Jennifer Detlor are praised for making the material easier to understand through engaging lectures and genuine care for student success.
Recent recorded grades — Spring 2025: 2.65 GPA, 21.1% A/AB (n=275 letter grades); Fall 2025: 2.96 GPA, 36.4% A/AB (n=382 letter grades); Spring 2026: 2.85 GPA, 31.9% A/AB (n=342 letter grades).
Historical reviews of Sonny Nimityongskul, Wendy Crone: Workload expectations vary significantly. Some reviewers find homework challenging but worthwhile, while others report a ridiculous amount of homework that does not help with test preparation or learning.
Historical reviews of Corinne Henak, Robert Witt: Lectures are frequently described as dry or boring, leading students to rely on textbooks or outside sources. Reviewers suggest that reading the textbook is often more effective than attending these lectures.
– average GPA
Approximate 80% prediction interval
The course’s semester-average GPA, not an individual student’s grade. The center uses 5 same-season terms, weighted toward recent results.
The range uses the finite-sample 80th-percentile rank of absolute errors from earlier same-season forecasts. Each forecast uses only records from earlier terms. At least four forecasts are required; bounds are rounded outward and limited to 0–4. This is an empirical estimate: changing instructors or grading policies can reduce its coverage.

Typical course in this group: letter grades.
1283 courses over the same term, each with at least 30 recorded letter grades. Cross-listed courses count once. GPA is not a measure of difficulty or teaching quality. The typical course is the median by recorded grade count; tied values are not counted as lower. Grade counts describe course scale, not unique students or typical section size.
Descriptions compare GPA with this group’s average: at least 0.20 higher or lower; otherwise close to average. Section size uses median recorded enrollment: small up to 30, mid-sized 31–99, large 100+. Lectures and discussion/lab sections are described separately.
