This guide is the best
This guide is the best anywhere in the internet. Other sites always try and sugar coat it, but here, it's straight down to business. I love it.
However, there is one thing it lacks: you're not getting enough challenge, all you're doing is reading. Without some sort of pop quiz at the end of each lesson, all the information you retained will be lost.
Reading is one thing, but if you don't put that information you learned to practice, it'll be forgotten.
I don't know if this is just me, but I'd love if this site had a small test at the end of each lesson, an exam at the end of a section and a major exam at the very end.
There is an anki deck you can
There is an anki deck you can use to review the different topics on this site, it's really good.
thanks for the guide.

Great guide! I just downloaded the iOS app. It's really useful, but I notice that it's missing the practice exercises. Where can I get them for my ipad?

Sounds like a fake review.

I just noticed there have been several updates of the iPhone/iPod app! (I downloaded version 1.0.x sometime last year but I mainly learn with the PDF so I never mind checking for updates.)
New features of 2.0.0 include "new content", as I read. Does this also affect the PDF version and is there also an update for the PDF? I'm getting slightly confused although I'm sure your grammar guide already covers about more than 90% of Japanese grammar!
Anyway, thank you sooo much for this awesome grammar guide!!!
I've been learning for 1-1/2 years now and I've recently covered causative and passive verbs. Although I'm no native English speaker I can understand everything.
Without this guide I think I couldn't have learned Japanese so well!
ありがとうございました!!
