Problems in educational rounds are generally straightforward and I've found them helpful for practising a new concept. I wrote a little python script for myself which uses the CodeForces API to fetch problems across all educational rounds, sorted by the difficulty in chosen tags. (There's no way as far as I can see to do this on the platform itself)

I'm sharing it here in case someone finds it helpful: https://github.com/yashrajkakkad/cf-educational.
