When I took my written test and all of my endorsement tests... Hazmat, Tanker, Doubles/Triples....it was all on a computer and was "multiple-guess" testing.....
Ummm, at the risk of sounding "snide"....if you need to have the "book open to take the test, me thinks you needs to study some more".
Cuz', if'n you don't know the answer well enough to take the test, whatchu gonna do when is goin' down da road.....and @#$* happens??? Look it up in da' book?
Study until you have it down pat, then study some more
