UCSC vs SJSU vs Community College during pandermic

It looks like most education institutions are planning to do online classes for this schoolyear 2020-21, due to the pandemic. Can someone paint a fair comparision of what rigor is like for all 3 types of institutions ? My worry is that if my kid goes to CC for the first 2 years, will he have to play catch-up when he transfers to university ? Intended major is Biology. Thanks!
