Details here.

Additional details and notes:
- This year we have a non-flash submission page and score page, both of which can be accessed via mobile. We still recommend using a PC/laptop for the best experience.
- We will also have penpa links for online solving for all rounds. The participants will still be expected to come back and enter the answer key.
- We will be mailing the top Indian solvers after Round 7 itself to confirm their participation in the offline event. We expect the changes from the last round to be minimal and easy to account for, and it will enable us to plan the offline finals closer to the end of the online rounds.
- Of course, as we learned in 2020, the plans of the offline finals are all "subject to change".
