Oh I totally missed the part that you were asking for BEC, haha. That's actually a good question, and I'm curious myself now. Since the final reviews for Reg/Aud mainly focused on the simulations…I wonder what the final review for BEC is like!
Generally, I only do the MCQ's 1-2 times for each lecture. The only ones I do the second time are the ones I missed on the first go-round. I try not to allow myself to memorize the answer to any MC, but rather the reasoning of “why” it's the correct answer. I also make sure I thoroughly understand the material before doing any MC's–how I do that is another story, lol. Then, after I've completed all the lectures, I'll go back over all the MCQ one more time. I don't even worry about the ones I miss at that point, just reassure myself on the reason of why the correct answer is correct.
That's when I move on the Final Review…which is usually about 1 week before the exam. Then I'll go back and do the Final Exams on the main software the day before the exam. So to answer your question, I guess I have a fairly good handle on the material before I get to the Final Review so that I can focus on the simulations and not be learning concepts that I should already know.
Sorry for the long-winded post and if it doesn't make sense. Tax season has ruined my thought process.
