I managed to solve two questions but my rating decreased. Is there minimum number of questions need to be solved to get rating.
In competitions like cookoff, it depends on different parameters like accuracy, quickness to get a better rank, and your rating mechanism depends on your rank.
ratings do not depend on number of problems u have solved
it depends on the rank u got in that contest
your rating was 1554 …and u got 2200/3600 users …but u are expected to
do better…so ur ratings were decreased
u made ur first submission at 10:25 …but i dont think u spent 45 mins on that…
so u should start early @9:30 and make sure u dont make so many wrong submissions
since they have penalty in cookoffs
