I'm a first year as well so clearly haven't sat step 1 but I did score very high on my first exam (Cards, Pulm, basic sciences).
I skip all lectures, I don't write any notes. What I do, do is try remember everything I learn, I feel like writing notes is just a time waster because all the info is already A) on the slides or B) on the internet readily available. Some of my class mates have 50+ pages of notes we have per case, I have about 4-5 pages listing all the things I can't remember about the case which i'll review frequently, writing 50 pages of notes is just far too time consuming.
Watch videos, do practice questions, examine the models, use diagrams and imagery, overlap material, understand why a drug may cause it's side effects and why it has certain contraindications. Go over things all the time, mix and match your study with various organ systems each session, use multiple resources. Avoid coffee shops or any public places for study, find a room with a whiteboard bring your mates and discuss and info dump everything you guys know.
When I do write things down (which is a lot) it's either an area or something about a certain drug I may have forgotten e.g the MOA etc and these things will be the first things I review the next day and I will keep reviewing them (like anki cards). E.g my last note was Left testicular vein drainage because it's not the same as the right and I forgot. Nobody else I know does this and everyone keeps saying I have good memory; well that's because I like to use it and push it.
Study smarter not harder.
