Singapore is reopening their schools, including junior colleges, on a modified bi-weekly schedule.

SINGAPORE - Schools will reopen on June 2, but daily classes on school premises will be held only for the graduating cohorts of students in Primary 6, Secondary 4 and 5, who will wear masks or face shields while attending their lessons.

All other students will alternate weekly between home-based learning and classes in school. All student care centres will also open from June 2.

This approach would make sense for the US too. For college freshmen and sophomores, taking community college is probably the most effective alternative to online university courses.
