Historical instructors & teaching patterns
Past student reviews · Jeffrey Schmidt, Yibin Pan, Albrecht Karle
Jeffrey Schmidt’s teaching was mixed: one student found exams directly reflected lecture slides and quizzes, making an A achievable with study, while another found his lectures rushed and unhelpful. Yibin Pan’s exams consisted of multiple-choice questions often drawn from homework, and students could use two-sided formula sheets. Albrecht Karle’s lectures were described as monotonous and poorly structured, though discussions proved more helpful.

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.
8 earlier forecasts · 0.10 GPA average error.

About this comparison
1280 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.
