When searching for courses on ASU's course catalog, Rate My Professors' Overall Rating will be shown next to each instructor. Mousing over the rating will show more detailed ratings as well as reviews. Clicking the popup or Overall Rating will open that professor's page on Rate My Professors in a new tab.
Autorun can be disabled so that ratings are only shown when the ASU Professor Ratings icon is clicked. This option and others can be accessed by going to the options menu of the extension by right clicking on the icon and selecting Options. The options can also be accessed through the chrome extensions page (chrome://extensions).
