I always intentionally allow more time that would be necessary. In my opinion, quizzes like these should not be a race against the clock. It's much more satisfying if you can take your time in trying to reach 100%. Of course it may sound non-sensical for people who find my quizzes too easy, such as yourself, but if doing these quizzes as fast as possible is your cup of tea, you still get to see how fast you do them. Allowing more time doesn't take anything away from anyone.
"Ben" works for Episodes I and IV Kenobi but doesn't work as a type-in for Episodes II and III. Not sure if it's supposed to work for all Kenobis or just Episode IV
