Using Genki when my teacher uses Minna no nihongo?

Hi, I recently started Japanese lessons from 0 with a teacher. She uses Minna no nihongo, but the study materials she creates are not intuitive for me, and the book even less given it's all in japanese.

Would it make sense for me to buy genki and study it along the way? Or should I stick to whatever she provides even if it's very hard to study for me, as her slides are basically just words put there or drawings? (I cannot change teacher)

Thank you in advance
