Study mode is unfailable so you'll have to sit through it regardless. I would recommend just unlocking this as you go for other achievements by getting all of the questions right, but you theoretically could get through it without paying attention to anything you answer.

Just use single controller mode with 8 players.

This is also the best way to grind experience for the 225k you need to reach Grade 6 in the Permanent Record. If you get every question right on every controller, you will get around 20k points.
