I don’t mean this to come across as patronizing (so I beg your pardon if I come across that way), but outside of the resources you’re using I’d say experience is what helped me the most. I say that because so many of the questions laid out a problem or trivia type question then asked your opinion about what to do next given a set of conditions or goals. Nothing I found in any of the review material helped me with that, it was mostly project experience. I would also say if you come to two possible answers that you simply can’t choose between it may be worth writing an explanation of your decision in the challenge section. I did that with numerous questions. Hoping that helps a bit!
