Marugoto books

I recently read this Tofugu article A Review of Marugoto: Japanese Language and Culture Textbook but the article never mentioned what JLPT levels the Marugoto books are mapped to. Does any one know their corresponding JLPT levels? I know that the Marugoto series focus on conversation but still would be nice to know the grammar level involved…

A1 is N5, A2 is N5 with hints of N4, A2/B1 is N4, B1 is N4-3 and B2 is N3, from what my teach told me

I’m currently using A1, so if you need any more info from these in specific, lmk!
