I found these groups which are awesome for the beginner coders :

1. Assiut University Training — Newcomers

If you complete the above one try a bit harder now as we can't do only Problem A forever, It's only good if you try to escalate from where are you right now and don't just stick on easy ones.

1. 30 days (a bit harder)

A special request to Mike to integrate something so that a beginner can find a group to practice similar problem as to their rating.

Please comment for more groups for beginner...
