Sounds like a clear misuse of being able to audit a class.
If they're actually doing the work, and are meeting people to work with, it doesn't matter (edit: see edit at bottom). In any given class, attractive people get more help from peers.
Edit: I just realized these are math and science classes for non majors. I thought it would be something like economics or geology or something, where having a STEM background would help but not directly.
In this case, this is inappropriate and I don't think these students should be taking this class at all.
