Underrated thread

I used to participate in a lot of contests (Mainly in my country) and got a lot of benefits from that such as instant admission to any university in my country and scholarships. Being able to solve complicated problems, landing a job in any major CS company is piece of cake. Though I don't do it anymore because it doesn't pay off in college.

Here is my certificate from the last ACM competition in my region. Georgia Tech took first place (with triple the score). I'm ok with second place though.
