Can I count on the Kodansha Kanji Learner’s Course to learn both the kanji and the vocabulary required for JLPT, both at once?

I have the book, and it gives a lot of vocabulary along the way, that is made both to learn the kanji "in situation", and to learn the vocabulary itself, which I guess helps for both.

I'm targeting N1 at some point, does the course's vocabulary cover a big part of it, or is it far from that and I need to separately specifically learn a lot of vocab lists?

I guess it's answer 2, but, just in case.

I'm planning to pin vocab lists on my walls so I will see them even when I'm not thinking ok let's study, and learn them half-passively, and I was supposing I'd learn the kanji separately.

But I have limited availability ;and I need to improve my level and get my N1 at some point), so I just happened to wonder if pinning the kodansha pages instead would save time and be more beneficial, or not.

(Yes it's a lot of pages, they wouldn't be pinned all at the same time 🙂 and yes, copies to get both sides of the pages.)

Would you have any knowledge on that?

Thank you very much in advance!
