Calculate your Astronomy 100 Grade

This is a simple tool for calculating your grade in Astronomy 100. My hope is that by understanding how various parts of the course affect your grade, you will be able to direct your energy and time appropriately. Feel free to send me a message if you have questions about your grade calculation.

Your grades come from the sums of the following scores:

I will drop the 3 lowest scores from your in-class quizes before they are added up.
