I apologize if this is already documented somewhere; I looked through the wiki but didn't see anything.
I was wondering if it's possible to give my students the option of redoing a problem set with a new randomization, for practice rather than for a grade?
Thanks for any help!
A common practice is to have them log in as a guest using the "practice1", "practice2" etc. logins. They get a new randomization --- their grades are not recorded. They get a different randomization for each practice user.
To add the practice_i logins in they are not already there, go to the classlist
editor page and import users from the file demoCourse.lst -- that will add
9 users named practice1 through practice9 and will activate the "guest login" button on the login page.
Let us know if this works for you.
