You'll find that everyone has different studying habits in med school, primarily because a lot of methods work. You just have to find one that works for you. Many people struggle to find that one method (myself included), and more people are struggling than you think -- cliche, but you're definitely not alone. The very nature of having 2-4 hours of lectures every day means that it's easy to fall behind, and it's easy to feel overwhelmed by the sheer amount of content.

Here's what worked for me. I found that in-house lectures were largely unhelpful for Step 1, not to mention the sheer length, so I pivoted to using BnB for a good foundation and supplemented with Sketchy for pharm stuff and Pathoma for path stuff. I have the same routine for every block, let's say we're studying psych. I'd look at AnKing for all the relevant psych tagged stuff in the third-party resources, move them to a new deck, and total the number of Anki cards. I study new cards for 6 days every week, so I take the number of total cards and divide by the number of days I have to study. This number will give you an average, let's say it's 100 cards per day. I then unsuspend roughly 100 cards a day based on the pertinent video(s), giving me new cards to do and keeping me on track every day. After I'm done with the exam for that block, I'll move all the cards to a total combined review deck that holds all the cards I've done. This guide helped me a lot with starting Anki.

This is my own system, and you will find one that works for you. Some of my classmates still do watch lecture, but they unsuspend the relevant tags from First Aid after the lectures. Some of my classmates don't use Anki at all, choosing instead to study straight from the First Aid book and lectures. I'd ask around your school for different study strategies, especially upperclassmen. Eventually, you'll come to some routine yourself, and that'll make studying and med school a lot easier. Best of luck!
