Need appropraite plugin!

Hey,

Need help ASAP!! Im currently using the Buddypress plugin and the Custom Community theme in my WordPress site. My site is for a project, it is a hub for students of my university.

I want there to be something where users can rate teachers or courses. What plugin should I use for this? It has to be a separate page and rating for every teacher should be separate.

I am not learned in coding or anything, so please if anything technical is involved guide me through the steps.
