I'm trying to understand why someone should be issued a CPA license if they cannot communicate effectively.  Business communications is part of the curriculum in college.  I don't know if there is any real suggestion but to practice your communication skills.  THEY ARE IMPORTANT! 

If you feel you don't need these to perform accounting duties professionally, you better get almost every question correct.  If no other portion of the CPA exam is difficult for you, then certainly the questions on the BEC should be a breeze, honestly.  I took the test with nothing more than the Wiley question bank, studied for 4 days and I was so suprised at the ease of the questions on the exam, I went through each one 3 times.  Of course, I haven't gotten the score back, and I know there have been suprises...but I'd be HIGHLY suprised if I failed that thing.

The BEC exam is weighted 85% MCQ and 15% written communication, so it's absolutely possible to pass without it.  To Acaboody's point, you should absolutely practice your communication skills regardless.  If you're planning to work in a country where English is the primary language, your career would be better served by improving your communication skills. 

With all of that said, your use of English seems decent enough that you're not going to get a 0 on the WCs.  I know many native English speakers that write more poorly than you.  Good luck!

I'll keep it real ... a blank WC = failing score.
