I got up early each day and camped out in one of the study rooms of my med school. I think there is a Laffer-curve like relationship between comfort and productivity. Studying in my apartment was too comfortable (and too distracting) for every day studying for Step 1. When I study at home, I often start lying down on the couch while reading, spending time making tea, watching Netflix, etc. This was fine when I had more time and didn't really have specific goals I was trying to keep, but it would not have worked for Step 1.
My routine was that I got up early enough that I could reliably get a room, threw some chilled coffee, sugar, cream and ice in a thermos and shook it up, grabbed a yogurt and a spoon, and headed to school. When I got there I watched YouTube and relaxed for 15-30 minutes while eating my breakfast and then I was away to the races.
I did very well on Step 1 so it worked for me, but I also have ADD and accordingly there are a number of things that went into my calculus with this decision that may not apply to others. Your mileage may vary.
