What do you think – worth a try? Wasted money? Quite possible?
I’m hesitant :x
Update: I should be perhaps a bit more concrete. So far I hadn’t had problems with the grammar presented in Kanzen Master JLPT2 and I only made 2-3 mistakes in the test section which makes me quite confident. I had a brief glance through some available mock exams and must say that the vocabulary/kanji section will be a piece of cake for me, where as I recognised how bad my listening would fail at the listening section. The ressources I found where for the old JLPT2, but I suppose not much changed concerning the new level (perhaps more grammar orientated towards JLPT1 already). By the time of the test I will have reached already about 8000 words, so this will be plenty and also enough kanji (~80% of jouyou kanji)..
