Is the style of problems at div3, edu are different with div1,2?

Revision en1, by gs15120, 2019-07-30 19:46:37

I'm solving problems of difficulty 2000~2300 at the problemset.

But a funny thing is, problems from div3 and edu is much more easier than from div1,2 for me. Even the difficulty was inverse.

Is it because the style of problems? Or the difficulty is not accurate?
