The three are among 562 students from all 50 US states and seven foreign countries in this year's 92nd national spelling bee.
Any student who spells a word wrong during the oral rounds is automatically eliminated from the competition.
Amulya Ganta is competing at Scripps for the first time and says it's a big deal for her to represent midland on a national platform. It is an invitational program providing an additional path for champion spellers to join the bee.
The other students come from all 50 states, territories and Department of Defense schools in Europe.
The champion receives $50,000, while other top finishers will take home smaller prizes.

Finals begin at 10 a.m. and run until about 2 p.m. The prime-time portion will air from 5:30-7:30 p.m. on ESPN and the ESPN App.
