I am thinking of getting some ideas together to write an ebook about how to pass the JLPT.
My reasoning is that there are a lot of books out there that help you with the actual grammar / vocab / kanji (albeit usually in a fairly unexciting format) and you can buy practice papers (although they are expensive). However, there doesn't seem to be much information about the test-taking aspect - i.e. tips on how to take the test itself in the most effective way to mazimize the chances of passing.
I would be interested to hear if there is anyone out there who would be intested in this kind of information - and what else would you want to know?
