League A and B both have 12 teams that are divided into 4 groups of 3 national teams. League C is made up of 15 teams that are broken down into 3 groups of 4 teams and 1 group of 3 teams. And League D is made up of 4 groups that consists of 4 teams in each. The teams were placed in each league based on their UEFA rankings. For example, the top 12 teams are in League A and the next 12 teams are in League B and so forth.
There will be teams that are promoted and other teams that will be relegated. The last teams in League A get relegated to B, the last placed teams in B get relegated to C, while the top teams in League B, C, and D will get promoted to the respective leagues above them. In League C the worst 3rd placed team will be relegated to League D. Each team will play their opponents in their group twice, home and away.
League Finals is a 4 team knockout tournament that consists of 2 semifinal games, a 3rd place game and a Final to determine 1st, 2nd, 3rd, and 4th place.
Jonathan Wilson presents perhaps a better explanation than myself as I attempt to really communicate at a simplistic level.
Teams are in the current groups and leagues, but the positions teams are in their group is random as most teams have not played a game. Teams in promotion and relegation spots are not concrete.
