Isn't Austin still banned from performing music in this episode? Luckily Jimmy wasn't around to notice him performing and singing in Spanish in front of Senora Gomez at the Senior Carnival.
No explanation was given as to the exact time Austin was supposed to take the test, nor did Senora Gomez ever think about moving the time to do it to make up for Austin oversleeping.
What Classes at School had been Austin been doing before he officially became a Senior after passing the Spanish Test is unknown.
Austin's tour the previous year took place in the Summer, when there was no school.
It's not the first time that Coach Simmons has done a different sort of job. He's also been in charge of the School Play in the past.
Austin's parents (who are rarely seen anyway) never do seem to notice Austin never returning from the A&A Music Factory the night before the Spanish Test.
