I can only imagine this sort of study guide making things harder.
You'll read 1582 AD on your test only to have your thoughts briefly wander back to Ako's delicious armpit before seriously contemplating just how she managed to write in such a difficult to reach spot so legibly. You'd then remember the writing on her inner-thigh, think about how hard that must have been, and that's it, game over. You're stuck thinking of Ako's inner-thighs for the rest of the period.
