Good news...I guess. Levels 1 and 2 of the JLPT is now being offered in the summer time, as well as in the winter. I picked up my application the other day for the 1st level and expect to fail it once again in July. The deadline for applications is May 1, so hurry if you haven't already bought yours and sent it in.
Oh yeah, if you're interested in 1級 grammar, I did a quick series on grammar explanations for last year's test. Have a look in the archives!
