your performance will change depending on the question bank, who wrote the questions, how you are performing that day, how focused you are, what format the questions come in (e.g. a set of 15 questions or a set of 40 or a set of 20 on paper). you spend an awfully large amount of time focusing on every single drop, uptick, and/or adjustment of your scores resilient. in fact, i will repeat what i've mentioned to you before: don't lose sight of the forest by focusing on the tree. there are simply too many factors for anyone on this board to give you a reason for why you saw the score drop - only you can figure that out.

great resource
