Google Forms has the ability to create quizzes with an answer key containing possible correct answers. For instance, if you wanted to forgive misspellings, then your answer key could include "Barack Obama", "Barak Obama", "Barrack Obama", etc. Google Forms has the ability to use regular expressions for input validation. Is there any way to use regular expressions in a quiz's answer key, e.g. "^Bar+ac?k Obama$"?
