Usually I try to hold myself accountable and always do my best on a round, even if that means submitting when I almost certainly know I will lose points. The only exception to this was last round, because I am within 3 points of teal and would very much like to see it. I'm curious about other peoples' strategies, would you submit problem A if it took you 30 minutes to solve it? Or would you submit problem A if you are almost certain you can't solve B or C?
I always submit and try my best
