## Summary

The last 48 hours before USMLE Step 1, from Part 7 of the video "How to Pass USMLE Step 1 in 2027 (Day 1 to Exam Day)". The day before, the goal is to be a little tired, so you fall asleep by 9 p.m. and get 8 hours of sleep right before the exam. Revise only First Aid's Rapid Review section and your weak systems until 5–6 p.m., then close the books for good. Eat dinner, take a light 45–60 minute walk, and turn the lights out at 9 p.m. On exam day, run the 280 questions as 14 sets of 20: 3 deep breaths after each set of 20, and a longer 5–7 minute break after every 40 questions to use the restroom, hydrate and take simple sugar.

## Key facts

- Example: exam on 10 October. Sleep at 2–3 a.m. and wake at 6–7 a.m. on 9 October
- Why: if you are well rested on the day before, you are more likely to be anxious and not sleep the night before the exam
- Day before: Rapid Review section and weak systems from First Aid, until 5–6 p.m. at most; nothing new
- Books closed after 5–6 p.m.; dinner; light walk of 45–60 minutes; home by 8–8:30 p.m.; lights out at 9 p.m.
- Wake at 5–6 a.m. on exam day = about 8 hours of sleep
- Exam day rhythm: 20 questions → 3 deep breaths → 20 questions → longer break of 5–7 minutes → repeat
- Longer break: restroom, hydrate, ½ a bottle of Gatorade, Tang or Glucon-D, or ½ a bar of chocolate; the brain uses glucose for energy
- Breaks never longer than 5–7 minutes; the real exam gives 1 hour of break time in total
- The same break and glucose rhythm is trained on every offline NBME first
