You have to post 3 posts by 11:59pm on Sunday. The system will automatically count your points.

Re: How does grading for discussion posts work?
Everytime you post something, whether it is a reply or your own post, the system gives you a point. Your TA will not check what you are posting, it does it automatically.

Re: Rusty on High School Chem [ENDORSED]
What is helpful to me is after a lecture, if I don't understand, I watch videos that explain each steps. So far it was been helpful, and it helps me understand how to solve questions on the homework.
