Past student reviews · Dan McCammon

One student found Dan McCammon’s lectures scattered and felt he expected them to understand too much material on their own.

What you’ll be able to do

  • Calculate equivalent resistance in a linear resistor network and apply Thevenin's theorem.

  • Calculate and measure the linear AC response of circuits of resistors, capacitors, and inductors.

  • Model and measure basic properties of P-N junction diodes, bipolar and field effect transistors, and circuits based on them.

  • Calculate, design, and measure basic properties of operational amplifiers and circuits based on them.

  • Analyze and build circuits using Boolean logic.

  • Record and organize observations, data, and results in preparation for keeping a laboratory notebook.

About this comparison

1316 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.
