This section of the course is the most difficult, so I want all of you to use the threaded discussion in this unit to post questions about the worksheets that are posted below. I would like all of you to answer each other's questions, but I will be reading the threaded discussion regularly and responding when necessary. I want to use this to help all of you. Make sure that you read others' threads so that you don't post the same question. You will not be penalized for typos, grammatical errors, or spelling mistakes. However, you must post a meaningful response in order to receive credit for the threaded discussion
