Students describe current instructors Abdollah Mohammadi and Sridhara Dasu as caring, knowledgeable, and engaging, with clear lectures and helpful demos. However, significant disagreement exists regarding exam difficulty and course organization, with some finding the material manageable and others finding it absurdly difficult and poorly aligned with instruction.
Recent recorded grades — Spring 2025: 2.99 GPA, 39.5% A/AB (n=291 letter grades); Fall 2025: 3.05 GPA, 41.6% A/AB (n=190 letter grades); Spring 2026: 3.06 GPA, 43.2% A/AB (n=287 letter grades).
difficulty & workload
Several reviewers report that exams are significantly harder than lectures or homework, featuring ambiguous questions and topics not covered in class. The course is described as disorganized, with lectures that are useless, incoherent, or difficult to follow.
Useful aspects include Mohammadi's humor, passion, and responsive nature, as well as the value of in-class demonstrations. Frustrating aspects include mandatory attendance requirements, incoherent lectures, and a disconnect between the conceptual focus of lectures and the application-heavy nature of exams.

About this estimate
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.

About this comparison
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.
