@setmefree, sorry for the late response, just got back from a busy day at work. When I studied, I found the Becker sims to be harder than the actual AUD sims that were on my exam. No guarantees that'll be the case when you sit for the exam though, keep that in mind.
At the same time though, I learned a lot from the sims as Becker now has videos explaining some of the sims, so I watched some of the videos and redid the sims and carefully read the explanations. Any gaps in understanding, I'd go back to the book/skills practice and review.
For MCQ, I used the Becker Questions mostly and then I did the Ninja MCQ. I think my trending score was somewhere in the 80s, can't remember what I got exactly. For AUD, the MCQs on the actual exam aren't that bad, it's just that you have to watch out for the wording in the question and in the answer choices.
Let me know if you have anymore questions!
