Would it be possible to move up to the next division of a championship even if you are 2nd? And also when you play group 1 D3 is there a probability of playing group 1 of D2.... Thank you for answering me 🙏

Yes, it's possible to go up depending on the dropouts above.

As for the groups, it doesn't matter, they're random at the start of each season

It's too late, you've already left
