Onamission,
I just got out of BEC at 3:00 pm today. As you are doing, I used Becker. Yes, there were some questions out of left field, but there always is on these exams. Don't let it get you frustrated. Remember, the examiners are testing our ability to handle stress and unexpected situations, as well. "Pretest". Remember that.
Becker was probably as good as any other material. Becker's software is the bomb, so I am happy to be using them. I did pick up Wiley 2010 also, for IT and supplemental tidbits. Becker did much better for variances, and IT on the exam was more inline to what Becker focused on.
I don't know if I passed or not, but I gave it hell, boy! Just like the other two exams I have passed, FAR and AUD, time was an issue and I essentially ran out near the end. I had 18 minutes and like 12 questions, with about 6 others marked.
I suggest to read on concepts you are not totally familiar with. And without divulging too much info, know all your formulas. Someone on this site had a "cheat sheet" with all of the formulas. Try to find it and write in your own notes and comments. I can send you mine if you want. PM me if you do...but just a warning, it's messy!!
