Hi @KendraChaney,

Unfortunately, there is not a great way to accomplish this.  It is one of the reasons that many here in the community, myself included, will recommend against using the same course shell for more than one semester.  Your school/institution could make a second user account for the student, or perhaps make another Canvas course for you to teach that student from.  Aside from one of those two options, you'd have to allow multiple additional quiz attempts for this student and allow multiple attempts for all students on assignments.

I hope this info helps, even if it's not exactly what you wanted to hear.
