Week 5 Assignment #1
This one is easy. You just have to email me about how things are going for you in the class. Questions to answer:
- How is the class for you?
- What are the most useful parts - take home assignments, code walkthroughs?
- Is there anything you'd like to have more of, or less of, or none-at-all of?
