There are many lectures and conference talks from university professors who are at the top of their field on YouTube. You might be able to find better content than what's available in your local university class.
For example, Robert Sapolsky's lecture series on Human Behavioral Biology at Stanford: https://www.youtube.com/watch?v=NNnIGh9g6fA&list=PL848F2368C...
Stanford and MIT both have lots of lectures on YouTube.
