Plz tell me whether Loc June challenge will help me improve my rating and rank on codechef or will it not affect at all?
No, it doesn’t. It’s just a challenge to increase the awareness of CP in school students!
In terms of practice, it can help you do better in rated contests, but thats it.
Only Contests conducted by codechef is rated…
It is NOT rated. But it can help you maintain the momentum of coding while waiting for rated contest.
