Spellers who correctly spell their third-round word were moved among the maximum of 50 spellers advancing to Thursday's semifinals if their score on a test of 12 handwritten spelling words and 14 multiple choice vocabulary questions administered Tuesday is high enough.

Since then, Yash has spent hours every day sitting on a couch in his family's home in Carmel Valley, studying lists of words and reading out of the dictionary.
"About an hour every weekday, and 3-4 hours on weekends," he said, when asked exactly how much time he spends each day.
Yash said he started competing in spelling bees after watching his sister, Samruddhi, compete. She made it to the countywide finals, but never advanced to the national competition. Still, he was inspired by her success and wanted to go even further.
