Check out the new website! Pages are coming soon with lots of updated materials. I have started a new github site where all the materials for courses will appear, to make it easier for you to find everything you need.
I have provided entire courses for you to take yourself, use for your classroom, etc. If you are an instructor and want to check out the answer keys, please drop me a line by using the email icon at the bottom of the screen.
Hoping the updates start working soon!
