Summary

1 / 6

Past student reviews · Reid Van Lehn

Lectures were derivation-heavy with few practical examples, and homework problems required significant use of Excel or Matlab.

What you’ll be able to do

  • Explain the terminology, theory and models that describe multicomponent, multiphase systems at equilibrium

  • Explain the terminology, theory and models that describe chemical reacting systems at equilibrium

  • Apply chemical thermodynamic principles to describe, analyze data, and predict properties of multicomponent systems at phase and/or chemical reaction equilibrium

Approximate 80% prediction interval

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

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.
