Summary

1 / 3

Recent recorded grades — Spring 2008: 3.08 GPA, 40.6% A/AB (n=32 letter grades); Spring 2009: 3.04 GPA, 47.8% A/AB (n=23 letter grades); Spring 2010: 3.23 GPA, 43.2% A/AB (n=37 letter grades).

What you’ll be able to do

  • Identify all major rock types and the minerals that constitute them.

  • Provide characterization of rocks (e.g., types of schists) based on quantitative mineral composition and fabric.

  • Articulate how all rock types are related to plate tectonic processes and fit into the rock cycle.

  • Characterize the basic physical (density, porosity, permeability, fracture patterns) and chemical (pH, susceptibility of weathering and dissolution) properties of different rock types.

About this comparison

789 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.
