BJT Business Japanese Proficiency Test Question

I've signed up for the BJT test held in June and this will be the first time I take it or any other Japanese ability test for that matter.

I don't think it's as popular as the JLPT but I'm wondering if anyone on these forums has taken it before? I want to begin studying, but I see several testing materials at the local bookstore and I'd like to get some advice on what books have worked best for other people or personal experiences.

Any information would be most appreciated.

I hope you're aware that they are two very differently focused examinations...
I passed the JLPT/N1 in 2010, after having started learning Japanese in 2000, and having lived in the country for most of 2003, 2005 and 2006.
I have been told that a lot of Japanese people even have trouble passing that level.
The business test is supposed to be even more difficult... but that also may be due to my having "mastered" plain, friendly, colloquial language, first =P
Either way, I really don't think popularity has anything to do with it.
アルト's books proved fantastic for me. If they do business-level Japanese, then, I'd probably recommend them
健闘を祈ってます！
(I'd probably say that JBT is like TOIEC and JLPT/N is like IELTS. Eh, I could be wrong =B )
