Size of lower level CS classes at UMassAmherst, Boulder, Binghamton, CalPolySLO?

We are looking at these schools, among others, for Fall 2021. I’m unable to access the class sizes for their current class offerings. Can anyone give me the class sizes for intro CS classes and other lower level CS classes at these schools?

You should be able to access course catalogs for prior semesters/quarters and look at each CS class that was offered for specifics, including enrollment. Here is UMass Amherst’s course catalog, just select the time period you want:

Thanks- I had been looking in the wrong area that required a username and password.
