Dont agree with above posts, make First Aid your best friend year 1 AND 2 and your life will be SO much easier, also FA is enough for most NBME shelf exams if your school uses them, from my experience, especially PHARM and PATH. Also using Kaplan/Qbook/Pretests along for shelf exams VERY helpful. I spent summer after year 1 getting my year 1 classes up to speed with FA again and I can't recommend this more. For me knowing FA by heart was KEY for Step 1 and if you already have the familiarity with it, your Step 1 studying will be < 1 month for sure. Keep in mind every single person here has a different strategy that worked for them so now 50 OCDs will probably counter post me with their own shizznet. Peace-out!
