PassPlus is a free Chrome add-on developed by Rushil Patel. This tool integrates PolyRating scores for Cal Poly professors into the university's PASS system. With PassPlus, students can conveniently view the corresponding PolyRating scores next to each professor's name. By clicking on a score, users are directed to the professor's PolyRating review page.

PassPlus aims to make cross-referencing PolyRatings and PASS easier for Cal Poly students. By providing quick access to professor ratings, students can make more informed decisions when selecting courses and professors.

In the latest version, 2.0.6, PassPlus has made improvements to accommodate the growing number of users. The refresh rate has been decreased to reduce server costs, ensuring a smoother experience for all users.
