Hi! I am new to codeforces. Yesterday I participated in my first contest Educational Codeforces Round 110 (Rated for Div. 2). And solved only the first question. Yes, I am new to CP. My rating is still missing. The only Rated section is empty and in All section mention the contest but it shows "= 0 (unrated newbie).

Is there a minimum number of contests I have to do to get my rating and why Educational Codeforces Round 110 (Rated for Div. 2) is showing up in ALL rather than Rated?

Sorry, It is basic, but I am new here.

Thanks!
