Results for multiple quiz in one course

Hello Heroes!!

I have created several courses in Articulate Storyline 360, in one of them the student take the same quiz twice, the first at the beginning of the course to check what knowledge the student arrives with and the other at the end of it to check what knowledge they leave with.

The inconvenience that I find is that from Storyline I am not able to create the rule to save both notes and report them at the end of the course, since until now I am only able to evaluate and show the note of the 2 quiz, losing the information of the first .

Pd: at the end the student only will get the certificate if 2nd quiz is pass(but we want to know the grades in both time she/he takes the quiz)

Thank you very much in advanced!
