I might be an idiot for this but the way this book is structured is confusing me, I have only the N3 grammar book and on page 58 it switches to a different structure for the grammar points that labels each with letters instead of numbers, what’s the point of this do I need to switch around from the lessons in the former part of the book and do these or can I just make my way through the numbered grammar and then go on to the grammar starting on page 58
