Is it possible to rate certain Seasons of Series? IF YES, then HOW?

Is it possible to rate certain Seasons of Series? IF YES, then HOW?

Maybe im stupid, but lets take this for example:

https://www.imdb.com/title/tt0472954/

Where do i have to click? Or can i really just vote for certain Episodes? Cause thats too much work for me.. I almost loved voting for Seasons on other Sites, cause then i can do some math and see the overall Rating. 

Would be really nice if some nice Person could help me! =)
