It has been a long time @codechef:disqus …

Please provide the link to leaderboard!

is there anyway we could get the questions??

No.

The leaderboard link seems to have some issues with displaying questions solved by a team.

Also, would it be possible to get a look at the problem set?

The problem set will not be made public.

can we get questions on codechef after onsite contest ends??

No. We will have a replay contest after all regionals end.

When will the replay contest take place?

How many WF slots for Chennai this year?

It is not final yet. It will be 1or 2. It is usually decided after all the regionals get over.

Will there be a mirror contest tomorrow? Is that the reason problem set is not visible.

Can we have replay contests ‘before’ the end of all regionals? They serve as an excellent practice before regional 🙂

No.
