Took BEC last night.  I agree with everything jl0329 said.  However, those questions require detailed reading comprehension and common sense to answer (Becker cannot teach you either one of those skills). 

Don't panic.  Just study the material and you'll be fine.

When I first took BEC last August I thought the same thing.  Where the F*&K did these questions come from??!!  That being said, it seems on the message boards that many people who used exclusively Becker felt the same way.  This time around I bought Roger CRAM and the Wiley online test bank.  I am so glad I did.  There were a few questions on the exam that came right from the test bank, and the rest were formatted very similar to the way Wiley presented them.  I also liked the Roger CRAM because I can't listen to long lectures and Roger gets right to the point with the calculation stuff.  I definitely had a few questions that I guessed on and I still don't know if I did well enough pass (does anyone ever know?) but overall I felt much more prepared this time around.  Bottom line, spend the $80-90 and get the online test bank.
