For people who self studied Biochem, what resources are best?

Testing 8/15. Currently in orgo 2. Taking biochem at uni from 5/13-6/22. I feel like I definitely need to self study prior to the course and treat course as refresher and extra practice.

Planning on self-studying throughout spring break and into the rest of march.

Is Kaplan books sufficient or are theres specific youtube playlists that are better?
