Summary

1 / 6

Past student reviews · Thomas Crenshaw

Information comes fast, making the course tough. Homework and quiz questions are written oddly, which can make it difficult to determine exactly what is being asked.

What you’ll be able to do

  • Recall and summarize the cellular, tissue, and whole-body metabolism and function of nutrients

  • Identify key elements of digestive anatomy that enable digestion and absorption of consumed nutrients

  • Explain the physiological processes required for assimilation of consumed macro- and micro-nutrients

  • Compare the similarities and differences in nutritional and metabolic strategies across species

  • Evaluate the interactions between nutrients, animals, environment, physiological status, and functions and integrate these interactions to understand whole-animal nutrition

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 · 0.21 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.
