In terms of physical likeness, the individual tests for purchase ie 80, 81,82 etc. ,how do they resemble actual test-day tests?

Are they exactly what to expect? if not what differences are there?

and to be clear not regarding the test itself, those booklets.

I ask because if I have the booklets (those thin ones from amazon) I should definitely use those for my first PT as oppose to printing them, obviously?

I was planning to anyway, but just wanted to know if there are any differences?
