I discovered that you can skip most of the quiz questions before the final boss battle. To do this, you must enter the final door where the questions start with only one life (will show in game as "x1"). Then when the questions start, you can just press A on the first two questions (They'll be on option 1), and since these answers are wrong, it'll take you to the continue screen. Once you continue, you'll start at the final boss battle.

If you enter the door with two or more lives it will not work, and as long as you have two or more lives you'll have to answer all the questions with the correct answers in order to proceed. Be careful with the treasure chest right outside the final door as it usually drops an extra life.
