I'm not sure if my post would help.
When I prepared for BEC, I used Becker Self Study, I did everything plus did all the questions from Wiley review book. However, on my exam day, few things I saw were really mentioned in either one of materials. I guess what I want to say is, for BEC, try to do as many MCQs as possible, because this exam is so random. and you have no idea what kind of question they would throw at you. If you are luck, you would get questions that your materials covered. If you are not, you will have to guess.
By the way, I got 100, 100, and 98 for my Final test one on Becker. So it actually didn't mean you would score that high on real exam.
I Can Do This!!!!!
