I'm not a fan of learning complex topics in CP. I prefer practicing the things I already know, or practicing by rating, not topic.
The problem is that, now that I'm preparing for EJOI, I have no idea if the basics will suffice, especially considering other people born after 2011 who will go to EJOI.
So what are the topics that you HAVE to know if you're going to EJOI? Also, are interactives/grader problems a thing in EJOI?
Thank you, and best of luck to everyone preparing for EJOI
