Becker is adequate for everything except IT (chapter 4), for which I would suggest supplementing with Wiley if you have time.  I say "if you have time" because Becker is not woefully inadequate for IT, but it does leave a bit to be desired.  However, plenty of people have passed fine with Becker alone.

I do think the BEC material is easier to grasp in that there is less material than the other exams have, but the exam seems to be graded most harshly.  Many people, like myself, got their lowest scores in BEC even though we came out of the exam feeling most comfortable relative to the other sections.

But if you are doing well on the Becker questions, you'll be fine.  Good luck on Friday!
