Does this make sense?
"I'm referring to the assignment where you had two students to a group and each group had a topic on which we had to do a presentation on."
Is this a run-on sentence?
Is the second "on" repetitive?

Yes, the second on is repetitive. I would suggest changing the last part of the sentence to 'each group had a topic on which to do a presentation'.
