Tutoring, unfortunately, is such a passive process that it often doesn't result in a notable score increase. It seems like it should, but things just don't work out usually. It often results in a false sense of security. Videos can result in this same sense of 'knowing' something when we may not actually know it (Dunning-Kruger anyone?)
You need to grind through realistic questions until it becomes a reflex more than a thought. I'm not sold on the materials you have listed above, because much of your time will be passive absorption of facts and concepts. You need to actively attack realistic questions and passages if you are going to see an increase.
I'd highly recommend you focus on doing every AAMC question you can find, at least TWICE. When you review the questions, try to rewrite some of their questions to make one of the wrong answer choices right. Try to get into the head of the test writer, because that allows you to see their nuances better.
I have heard of students who took AAMC materials and using Claude AI, generated additional study material. This got mixed reviews, but their scores were fairly impressive. So while what they studied wasn't well-packaged and full of pretty videos like the commercial materials, in the end it was effective. And as with all AI endeavors, it is only as good as what you input. You have to know the material to know if the AI output is good.
I want to offer one last chunk of advice with a huge qualifier. Look at previous posts to confirm my opinion here, as I could appear biased. BR materials have feedback at SDN that ranges from "trash" to "gold". Avoid that which is considered trash by most posters, and use the only the gold. I'll leave it to other posters to offer specifics about which of BR's materials are trash and which are gold. If you can find used BR books for cheap (and they can be found right here at SDN classifieds), then you can get a good amount of practice questions with unique strategies for one section of the exam.
Good luck!
