A few questions about ZCO 2017

This year I am participating in ZCO 2017 so I have a few questions related to it, it would be a really big help if anyone could help me out.
My questions are:

  • How many question come in ZCO?
  • What is the requirement to qualify for the next level?
  • What is the time limit for ZCO?

Once again thank you.

  1. 2 questions
  2. Usually one full problem is enough.
  3. It will be given in the question, but it should be like previous year questions. If you meant to ask contest time, then it’s 3 hours.

Thank you.

And its from 10 a.m. to 1 p.m. on the day
