Need to give as below difficulty levels.

  • Easy
  • Medium
  • Hard
  • Expert

But I saw many COOKOFF’s were just first Question was solved by 90% of people. Second Question ,even not reaching 10% of people.

Need to change in the difficulty levels. Thank you…!!!

Fastest fingers first will get good rank…!! All the best…!!


I think ,the incoming Jan 2019 COOKOFF follow above ones…Is it???

Many people are complaining about difficulty levels. So I will start my rant. xD

From my side, which many will disagree and they should.
I nowadays like imbalanced difficulty especially if I’m one of those who won the Fastest fingers.
Biggest rating change I see are those contest which has imbalanced difficulty this gradient.
I became CM on cf due to this.
As far as today’s round is concerned.
I made a typo which cost me one penalty and ~270 rank <=> -120 rating pts.
I was one of those who submitted problem in first 7 mins.

I really enjoyed solving the second problem. I got AC on the first submission. And that was worth solving it. => I got ~30 rank <=> +110 rating pts.
Overall I gained +230 pts by solving this single question (+ some laddus :P).

By seeing tags on editorials It seems worth solving the rest of the questions. Although I don’t know when I will do that :stuck_out_tongue:
I generally don’t complain about difficulty gradient until and unless questions are solved by many people. Because for me difficult question brings with them a room full of learning.
But difficulty and extremely difficult are relative terms.
