My humble 2016 JLPT N3 thread

I wanted to ask: Japanese for everyone grammar: how far does it take you? My ebook is around 360 pages long, I edited it, cut out the grammar points only, and put them together in a single document for memorization. This makes approximately 100 pages (A4), which is a lot, imo. I've looked on the net before, they say the JFE only takes you to N4 level....is this true?
I'm trying to assess how much raw material needs to be studied for N3. I have a good guess regarding vocab, reading and a little bit listening-wise,  but I'm clueless on grammar. Just how many pages needed to be studied?
