For the first episode, just register on the site and complete all 6 sets of questions. Apparently, there is a double-episode this week, and each of the episodes is divided in 3 sets of questions. Each half of the double episode is labelled as 01A and 01B. In the case it was just a long episode with only 1 Immunity Challenge and 1 Eviction, we would only take Episode 01A answers into account, and would re-open the next set of questions for the following episode.
Good luck, players! <3
