I like the fact that there is a ballet quiz, as I am a male dancer. Your definition of arabesque is incorrect as arabesques can be done a la seconde, derriere and devant and the arms are not opposite all the time of the leg. Also, I was wondering why key terms like tendu, frappe, battement, fondu, ronde de jambe, passé, develope, en de dans, en de hors, and pas de deux were not included.
Taglioni is spelled incorrectly. First school should specify Paris Opera (not just French School, as that is actually nothing), pique is not necessarily always a turn, so pirouette should at least be accepted. Glissades do not always change feet, the "next level" for training is a very vague question - could be many things really.
