Group A: 1-3, Group B: 4-6, Group C: 7-9, Group D: 10-12, Group E: 13-15, Group F: 16-18.

You're short on time, so it's impossible for each team to meet in pairs, so just play in the group, and half the high school students will be enough.

Therefore, it takes 3 full-time classes, and 18 classes in one school and one grade should be enough.

On the first day, Group A is 1 to 2 and Group B is 4 to 5, and so on.

On the second day, Group A was 1 to 3 and Group B was 4 to 6 in turn.

On the third day, group A was 2 to 3 and group B was 5 to 6 in turn.

After three days, the results of each group are counted, and if there is the same record, such as the record of 1 win and 1 loss of the three teams in the group, it will be determined by the net winning score.

The group with the highest record and the highest goal difference points will qualify.

In this way, 12 teams were brushed at once.

Rest on the fourth day.

The remaining 6 teams are called A, B, C, D, E, F (6 teams are not convenient to play the knockout round, because there will be three teams left after half of the brush).

Day 1 A vs. B, C vs. D, E vs. F

The end of the day coincides with Friday.

Ignore weekend holidays.

These teams will be arranged to play on 4 days in the next week, and the results will be counted after the end of Thursday, and if there is a similar record, it will be determined by the goal difference.

On Friday, the first-place finishers, the highest-winning players and the second-place finishers enter the finals to compete for the championship, while the third- and fourth-place finishers play third- and fourth-place finals.

Prizes will be presented at the end of the
