Goto a new passage with JavaScript

Twine 2.0.11 - Harlowe 1.2.2.
I'm using JavaScript to score points in a multiple choice test. I want to go to a PASS passage if the score is high enough and to a FAIL passage if it isn't, and I'm not sure how to use a JavsScript variable to determine which passage to go to. Please help. Thank you in advance.
