Agreed. This [0] and the subsequent lessons go onto explain that if clauses change depending on whether something is a fact, whether it is an invitation, whether it is volitional, etc.
I've been studying Japanese for years and I am at a basic intermediate level. I still find grammar hard to read, and even harder to produce naturally. I may just be particularly thick but I think saying "you can master Japanese grammar in a matter of weeks" is pretty misleading.
To be fair, all things considered, if you have to learn either language from scratch from a native language that has no link[1] whatsoever to it, I think English is harder than Japanese.
1. by which I mean, in the case of English, for example, if your native language is not french, german, etc.
In fact, I think English is harder to learn for Japanese native speakers than Japanese for English native speakers.
Yeah, I can't really speculate. It seems to me that the #1 biggest obstacle for Japanese speakers of English is getting past the Japanese education system, and actually speaking. Beyond that, I don't know.
But as a general principle, I believe that learning any new language is really, really hard. The people who claim to master languages in a few weeks are usually full of it (and by "usually", I mean "essentially always".)
