Option 1- -
All 1A's that recieve a 1 at region go to area (state prelims). Area competition is marched in San Antonio in the morning. Those that would advance (top 10) are at 'State' marching contest in the evening.
Option 2 -
UIL contracts a company to record all 1A performances and judge them by a panel at a later date just like region will be done this year due to covid. They can determine the best 10 bands and those advance to state.
