Well, it's made more or less clear the students know the Calamity is real in the various Japanese versions of it. Considering someone shot up the school two years prior as a result of the Calamity, people are more willing to believe in it. Plus the main character of the second season is Thomas's little sister.

The third season more than anything else deals with the people who are still alive from the previous two trying to help the current class deal with things. I've figured in the real world people will actually learn from their mistakes, so their solutions would actually be more and more helpful as things go on.
