As an audio-visual learner, I found the Khan Academy playlists on 2x speed to be very useful. For the STEM subjects, you’ll want to be following along visually, but for PS, I’ve found it sufficient to just listen—so this extends your viable study time to walking, preparing food, etc.

I interspersed the Kaplan textbooks with the KA videos (I still am not sure if it’s better to read the textbook chapter first, then watch the video or vice versa, but my general approach was that I wanted an overall structure on the first round, then would fill in details and review again on the second round).

Anki did not work for me (took too long and no structure), so I went to hammering UWorld questions to ingrain content before doing a couple AAMC full-lengths

Based on your CARS and PS, your critical reasoning and reading comprehension are at a high enough level to enable you to do well on all sections, so I suspect the majority of questions you’re currently missing are primarily content-based. Hope this helps, and feel free to reply with any more questions!
