You'd have to be basically ******ed to not pass. Think of it from the perspective of the instructors. They can either continue to drill it into your head for hours on end, until they are sure that you are competent, or they can say, "Dude, it is not my problem that this ***** can't grasp these concepts." Trust me, they will err on the side of "Let this person through and if they don't learn the material, it is their problem." These training sessions are generally meaningless political exercises on the part of hospitals to decrease their liability when physicians screw up. They can say, "Yes Dr. Jones killed that kid out-right, but we did our best to train Dr. jones, and he didn't follow the PALS guidelines that we told him to follow, therefore, you should sue him for all he's worth and go easy on us."
