This is exactly correct. Colleges and universities are

trying a few different strategies to reduce risk to their student population. At my school we are offering a lot of 8-week courses so they would be completed before a second wave. Plus the majority of the courses are completely online, with just art, science labs, and classes like nursing that have practicums continuing with face-to-face classes. Residential colleges and universities (mine is all commuter) have tough choices to make. The 3 state universities here in Arizona announced in-person classes for the fall, but delayed when students must decide where they will go until until June 1st (because so few students were ready to make a choice). The deadline is usually May 1st. After students decide, the universities may decide to announce that there will be only an online option. We'll see.
