Back in 2017, Y Combinator began offering a 10 week, once-a-year online course called Startup School. Part forum community and part video classroom, the program offers up a variety of lectures on topics like raising money or evaluating startup ideas, as led by YC partners and other entrepreneurs from their network. Three years and 40,000+ students later, they’re switching up the schedule; beginning in 2020, Startup School will now be running multiple times per year.
