Help with studying for a college class

It’s a long story, but basically, I have taken beginner Japanese 1 and 2 as well as intermediate 1. I’m starting on intermediate 2 this spring semester at college and I’ve had an almost year long gap between my last class and this one. I’ve been studying on and off between that time and now with my Genki 1 textbook, but I want to make sure I can keep up with my class. Do y’all have any recommendations for additional study materials to supplement my course? I appreciate any suggestions.
