Step 1 exam day: breaks, glucose and the 20-question rhythm
For IMGs walking into Step 1 this week. Your content is fixed now. What you still control is your energy, from question 1 to question 280.

What should I do the day before Step 1 and on exam day?
Start the day before a little tired, so you fall asleep at 9 p.m. and get 8 hours right before the exam. Study only your bookmarks, then close the books at 5 p.m. Eat dinner, take a light 45–60 minute walk, and lights out at 9 p.m. On exam day, run 20 questions, 3 deep breaths, 20 questions, then a longer break with simple sugar, like ½ a bottle of Gatorade. Never longer than 5–7 minutes.

5 p.m.
Books closed on the day before. Not opened again.
9 p.m.
Lights out. Up at 5–6 a.m. = 8 hours of sleep.
5–7 min
Every longer break on exam day. Never more.
The day before, in short
←
Sleep late the night going into it, so you're a little tired. Get your Glucon-D, Tang and chocolates ready for tomorrow. Study only your bookmarks, the cards you flagged all week in the FA Foundation Anki and the NBME Booster Anki because you didn't remember them. Books shut at 5 p.m. Dinner, a 45–60 minute walk, lights out at 9 p.m., and you wake up with 8 hours of sleep. The day before, hour by hour: the Final Day Protocol →
Exam day
Keep your energy up for all 280 questions
On exam day, knowledge is already fixed. What you control is your energy level, block after block. Your brain runs on glucose, so you plan your breaks around feeding it.
The real exam is 280 questions. You run them as 14 blocks of 20 questions each: a block of 20, deep breaths, the next block of 20, then your break. In this rhythm:
20 questions3 deep breaths20 questionsLonger break · 5–7 min… repeat
20
After the first 20 questions: take 3 deep breaths and carry on. Each set is independent. What happened in the last set is irrelevant.
40
After the next 20: get out and take a longer break of 5–7 minutes. Use the restroom, hydrate, and load simple sugar: ½ a bottle of Gatorade, Tang or Glucon-D, or ½ a bar of chocolate. Your Glucon-D, Tang and chocolates went in the bag the day before.

Repeat it to the end. 20 questions, deep breaths, 20 questions, out for a longer break. Every time.
The break rule:never longer than 5–7 minutes. 6 longer breaks of 5–7 minutes add up to 30–42 minutes. The real exam gives you about 1 hour of break time in total, so you always keep a buffer. On your NBME days, 40–45 minutes of breaks was right. The real exam has more break time because it's 14 sets of 20, not the 10 of an NBME.
You have already practised this. It is the same rhythm you trained on every NBME, because every NBME was taken offline: 20 questions in 30 minutes a block, a deep breath between sets, a glucose break every 40 questions, no phone, no pausing. Online NBMEs give you 50 questions in 75 minutes, which never teaches you this clock. Exam day is not the time to figure out your habits. Why NBMEs are always offline → · 24 hours of an NBME day →
And you've already done a full day. If you gave a full 280-question Vault Assessment or your 2 mock days, you already know how hour 6 feels. My students say the real exam felt shorter after it. The Step 1 assessments →
Not done a full 280-question day yet? Give the Vault Assessment14 blocks of 20, at the real exam's stem length, with a system-by-system report and an honest pass verdict. On the Vault plan it falls on day 27, before your final week. Assessment 2 is free for every signed-in student.
