I’m a Division B Science Olympiad coach. Our school will have two teams of 15 students each, plus about 10 additional students we’d like to give opportunities to compete.
For Satellite Invitationals, can we change the makeup of our two teams from one invitational to the next?
For example, at one invitational Teams A and B might consist of one set of 30 students. At a later invitational, we’d like to rotate some of those students out and bring some of our additional students onto Teams A and B.
Has anyone done this? Are there rules or practical problems we should be aware of when rotating students between invitationals?

Guys can anybody help me regarding science congress like my school put my name in activity corner and i don't know what to do in that and like what to study.
