I don't think remembering the question is a wrong thing nor does it send a wrong signal. As long as you know why you are getting the answer right and why other choices are wrong...you should be well set.
I pick on certain words in the question and think to myself, and whatever the first logical "key word" comes to my mind, I look for that option...if it's not there, I look for the next best guess, etc. This way, I'm def. getting the concepts down rather than just clicking on what I have memorized.
I have done passmaster MCQs at least 3x and even when I do them all at once, there's few that seem surprising or "hmm I don't remember this one." I do all the supplementary questions, so those surprises aren't something that I haven't worked on before...
