Keep asking until you find someone who can sell you the code, which is about two inches square, has a red border across the top, and has a grey scratch-off box like a lottery ticket. Only once during the semester will you need to copy this code into WebAssign. You will now be able to use WebAssign for the rest of the semester. Thus, it is wise to begin the assignment soon enough to be able to submit it on time. I can grant extensions electronically, moving a past assignment to the current assignments list.
Submissions are the the number of chances to have to submit the assignment.
You do not need to submit an assignment more than once, thus there is no problem if your assignment table shows that you have not used all of your possible submissions . Your score on the assignment is all that will count in your final grade. If the red letters don't appear, I have no comment for you, and you have received full credit. These assignments have no effect on your grade . The former is for your instruction, and the latter is for the benefit of WebAssign and myself.
