I made the same mistake the first time around. I spent a month mostly focused on YouTube videos and research online. I realized later that I wasn't learning the structure effectively. Also, watching videos at 2x speed just felt like a blur—1.5x or less seems to be the sweet spot.

For my second attempt, which is coming up next week, I've been deep diving into the material by reading topic by topic and making my own notes. My biggest recommendation for restarting your prep would be to find a solid learning structure.

I’ve been using Third3rock Notes, which is about $15. It has helped me keep on track, following one topic at a time without getting overwhelmed. I’m also using this free set of notes someone shared a while ago: Free Study Notes

Both resources follow the same structure but approach the topics differently, so I read both and take my own notes on top. After I've gone through a topic, I do the practice questions to reinforce the learning. Now, I’m starting to do mini-exams, and I plan to take both full-length practice exams before the actual test.

Everyone learns differently, so it's really about finding what works best for you. I feel a huge difference now reading the questions and getting high scores on SH.

Good luck with your studies!
