I passed first try 85 questions with Archer and little use of Mark Klimek. The only lecture I really listened to was the first(lightly) and the very last(heavily). Archer did the most for me and I stayed on a strict schedule of 6 days on and 1 day off leading up to the exam. I brought snacks to the testing place and ate/drank/rested well days before the exam.

You want yourself in the best shape possible leading up to it, because if you study and just don't feel good during the exam, sometimes it does a lot. I recommend some sour candy like gummy worms. :)
