Hi all. So I just took BEC this morning and figured I would give back to the community by writing about my experience. Obviously I cannot disclose actual questions but I will give you my insight.
First and foremost, based on all the posts I read reading up to taking BEC, I found that the exam really can test you on anything in the book. For example, someone above mentioned that cost accounting was really heavy on their exam. On my exam however, I don't think i had a single question. I had a bunch on variances but I personally don't consider that really cost accounting.
Aside from that however, here's some tips.
1.) COSO, IT, and Variances are a MUST study. Not even kidding, probably 80% of my exam consisted of this (which includes the SIMS and WC). Know these because they are basically free points if you just memorize them.
2.) I don't know if any of you saw the other post on NINJA that shared this but for variances, a cool mnemonic that helped me a ton is SAD PURE DADS. SAD is read backwards so difference = Actual-Standard. PURE stands for Price, Unit/quantity, Rate, and Efficiency. Then DADS is Difference x Actual or Difference x Standard. DA applies to P and R, DS applies to U and E.
3.) Know the formulas but don't stress over them. Again every exam might be different but from my experience there weren't many questions (aside from variance) where I needed to know the formulas. The MCQ's won't give you the formulas however, on the SIMS, it's virtually guaranteed that if you get one where you need to do CAPM, WACC, or any other of that Becker 2 stuff, they will give you the formulas in an exhibit (ie just like many of the SIMS in becker).
Overall my first testlet was roughly 75% computational for me while the 2nd testlet was virtually 100% conceptual (literally had 1 computation question). It seemed like the difficulty stayed the same so i'm not sure whether that was because I was over-prepared or because I didn't do well on the first teslet. Anyway, Good luck to everyone else who is planning on taking it in Q1!!!
