The problem with studying now is that we don't know what the event conflicts will be at next year's state and national tournaments. I'm really hoping that Rocks and Minerals doesn't conflict with Astronomy or Disease Detectives.
I'm pretty sure events within the same committee don't have conflicts. Astronomy and Rocks are both "Earth Science," so I don't think they will be scheduled at the same time. As far as ones in separate committees like Disease Detectives and Optics, hope for the best.
