You've done the work.

16-20 weeks of preparation. First Aid memorized through application. UWorld completed system by system. NBMEs taken offline with proper timing. Notebook reviewed. Weak systems strengthened.

Now it's time to execute.

Exam day is where all your preparation comes together. But it's also where students sabotage themselves with poor planning, bad sleep, wrong food choices, and mental breakdowns.

I've seen students with 70% NBME averages fail because they crumbled on exam day. I've seen students with 65% averages pass comfortably because they executed perfectly when it mattered.

The difference isn't knowledge. It's strategy.

Here's the complete exam day guide — from 2 days before to walking out of Prometric.

2 Days Before the Exam

This is where exam day preparation actually begins.

The Sleep Manipulation Strategy:

Here's something most people don't tell you: the night before the exam, you'll be anxious. You'll lie in bed thinking about questions. You'll struggle to fall asleep.

We're going to eliminate this problem.

2 days before your exam: Stay up late.

Go to bed at 1 AM, 2 AM, even 3 AM. Watch movies. Do something relaxing but keep yourself awake much later than usual.

Why? Because we're manipulating your sleep cycle.

What to do during the day (2 days before):

Light review only — skim your NBME notebook, flip through highlighted First Aid
No new content — you're not going to learn anything new in 48 hours
No full practice tests — you'll just tire yourself out
Stay relaxed — this is mental preparation, not cramming

That night:

Stay up late (1-3 AM)
Don't stress about it — you have one more day to recover

1 Day Before the Exam

This is the most important day for your mental state.

Morning: Wake up EARLY.

Despite staying up late, wake up at 6 AM or 7 AM. Yes, you'll be tired. That's the point.

You're now sleep-deprived by design. You went to bed late and woke up early. Your body will be exhausted by evening.

During the day:

Take a walk — get outside, move your body, get fresh air
Light workout — nothing intense, just enough to tire your body physically
Light review only — skim your notebook one final time, review your biostats cheat sheet
No heavy studying — absolutely no UWorld, no new NBMEs, no cramming

Stop studying by 5-6 PM.

Put everything away. Close your laptop. Put your phone on do not disturb.

You are done studying. Nothing you do in the next 12 hours will improve your score. But anxiety and poor sleep can definitely lower it.

Evening:

Eat a good dinner — something you enjoy, nothing too heavy or unfamiliar
Watch something relaxing — a movie, a show, something that takes your mind off the exam
Prepare everything for tomorrow — clothes laid out, bag packed, ID ready, snacks prepared
No studying — not even "one quick review"

The magic happens:

By 7-8 PM, you'll be exhausted.

You stayed up late the night before. You woke up early. You walked and exercised. You've been awake for 13-14 hours on minimal sleep.

Your body will WANT to sleep. You won't lie awake anxious. You'll fall asleep within minutes because you're genuinely tired.

Go to bed by 8-9 PM.

This gives you 8-10 hours of sleep before a 6 AM wake-up. You'll wake up refreshed, well-rested, and mentally sharp.

This sleep manipulation strategy eliminates pre-exam insomnia. I've used it myself. I've recommended it to all my students. It works.

Exam Day Morning

Wake up time: 6 AM (or 3 hours before your exam)

First thing: Do NOT study.

Not one page. Not one question. Not "just a quick review."

Your preparation is complete. Opening a book now will only create anxiety ("Oh no, I forgot this!") or false confidence ("I know everything!"). Neither helps.

Morning routine:

Shower and get ready — Normal routine, nothing unusual
Eat a solid breakfast — Something you've eaten before, something that sits well. Eggs, toast, oatmeal, whatever works for you. Avoid anything new or heavy.
Pack your break supplies:
- Gatorade or sugary lemonade (NO caffeine if you're anxiety-prone)
- Chocolate bars or glucose tablets
- Light snacks (granola bar, nuts)
- Water
Check your documents:
- Valid ID (exactly matching your NBME registration)
- Scheduling permit
- Confirmation email (on your phone)
Leave early — Aim to arrive 30 minutes before your appointment

The Drive to Prometric (10-15 Minutes Before Entry)

This is your final mental preparation.

What to listen to:

This is NOT the time for last-minute podcasts about renal physiology.

This is the time for pump-up music. Energy. Confidence.

Here's what I listened to before my exams:

Michael Jordan Bulls Introduction music
Jon Jones motivation videos
High-energy songs that make you feel unstoppable

Whatever music makes you feel confident and powerful — that's your pre-exam playlist.

The mindset:

You've done the work. You've completed First Aid. You've done 3,800+ UWorld questions. You've taken 8 NBMEs. You've reviewed hundreds of incorrects.

You are prepared.

You're not walking into this exam hoping to pass. You're walking in ready to execute what you've trained for.

This is your moment. You've earned it.

At Prometric (Check-In)

Arrive 30 minutes early.

Check-in takes time. They'll verify your ID, take your photo, scan your palms, explain rules, assign your locker.

What to expect:

You'll store everything in a locker (phone, wallet, snacks, drinks)
You'll keep your ID
You'll get a locker key
They'll give you a laminated notepad and markers (or scratch paper depending on location)
You'll be escorted to your testing station

Don't rush. Take your time with check-in. Get comfortable. Use the restroom before starting.

During the Exam: The Block-by-Block Strategy

Total structure:

7 blocks
40 questions per block
60 minutes per block
280 questions total
~48 minutes of total break time

Your break allocation:

You have 48 minutes to use however you want. I recommend:

6-8 minutes between each block (after blocks 1, 2, 3, 4, 5, 6)
That's ~42-48 minutes total

Don't skip breaks to "finish faster." Your brain needs recovery. Your body needs fuel.

The Two-Pass Method (Every Block)

You've practiced this on NBMEs. Now execute it.

First Pass (40-45 minutes):

Go through all 40 questions making quick decisions.

Know the answer → Mark it, move on
Unsure between 2 options → Circle question number, write "A/B", move on
Biostat question → Circle it, skip for now, move on
Completely lost → Make best guess, circle it, move on

Do NOT spend more than 1.5 minutes on any question during first pass.

Goal: See all 40 questions within 40-45 minutes.

Second Pass (10-15 minutes):

Do all biostat questions first (5-6 minutes)
Return to circled questions
Make final decisions with fresh eyes
If still unsure, trust your gut and move on

You MUST have 10-15 minutes remaining after first pass.

On the real exam, questions are longer and trickier than NBMEs. If you barely finished NBMEs with 15 minutes remaining, you'll have 5-8 minutes on the real exam. That's your safety margin.

If you practiced correctly, this timing will feel natural.

Break Strategy (Between Every Block)

After each block, take your full break. Every single time.

Duration: 6-8 minutes

What to do:

Stand up and stretch — You've been sitting for an hour. Move.
Use the restroom — Every single break. Even if you don't feel like it. You don't want the urge during a block.
Hydrate with something sugary — Gatorade, lemonade, juice. Your brain runs on glucose. You've just burned through mental energy for an hour. Replenish it.
Avoid caffeine — If you're prone to anxiety, caffeine will make it worse. The sugar from Gatorade gives you energy without the jitters.
Eat a small snack — Chocolate bar, glucose tablets, a few nuts. Keep your blood sugar stable.
Don't think about previous blocks — The questions are done. You can't change your answers. Dwelling on "did I get #23 right?" only creates anxiety for the next block.
Mental reset — Take a few deep breaths. Remind yourself: "I'm prepared. I've done this before. One more block."

What NOT to do during breaks:

Don't try to remember questions to look up later
Don't calculate how many you think you got wrong
Don't check your phone (it's in your locker anyway)
Don't skip the break to "get it over with"
Don't panic about hard questions you encountered

Each break is a reset. Use it.

When You Hit a Hard Block

It will happen. One block will feel brutal.

Every question seems harder. You're circling more than usual. Your confidence wavers.

What to do:

Stay calm — Hard blocks happen to everyone. The curve accounts for this.
Trust your training — You've done thousands of questions. Your instincts are good. Trust them.
Keep moving — Don't freeze on hard questions. Make your best guess, circle it, move on.
Remember: A hard block doesn't mean failure. It means you're being tested at an appropriate level.
On your break: Shake it off completely. The next block is a fresh start.

The truth about hard blocks:

Often, blocks that FEEL hard aren't actually that bad. Your anxiety makes them feel worse than they are.

And even if a block was genuinely difficult, the curve accounts for it. Everyone found it hard. Your percentile matters more than your raw score.

Don't let one hard block destroy your confidence for the remaining blocks.

The Final Block

Block 7. The last 40 questions.

You're tired. You've been testing for 6+ hours. Your brain wants to shut down.

What to know:

This block counts the same as Block 1 — Don't slack off because you're tired.
Your training prepared you for this — You've done 7-block simulations on NBMEs. This fatigue is familiar.
Use the two-pass method exactly as before — Don't change your strategy because you're tired.
Sugar is your friend — During your last break, take extra glucose. Give your brain fuel for the final push.
Almost done — 60 more minutes. That's it. You've spent months preparing for this. Give it everything you have.

After the Exam

You'll click "End Exam." A survey will pop up. Answer quickly or skip it.

You'll see a screen that says something like: "Your exam has been completed. Your results will be available in X weeks."

You won't get your score immediately. Step 1 results typically come 2-3 weeks later.

When you walk out:

Don't try to remember questions — It's over. Trying to recall questions to look up answers will only drive you crazy.
Don't discuss with other test-takers — "What did you get for the question about..." NO. Different people had different forms. Comparing helps no one.
Celebrate — You just completed a major milestone. Regardless of the result, you showed up and finished. That deserves recognition.
Rest — You've been grinding for months. Take a few days off. Watch movies. Sleep in. Eat good food.
Trust your preparation — You did the work. You followed the system. You executed on exam day. The result will reflect that.

What Happens If You Felt Bad About the Exam

Almost everyone feels bad after Step 1.

The questions were weird. You circled more than expected. Some blocks felt impossible.

Here's the truth:

The exam is designed to make you feel uncertain. They test edge cases, unusual presentations, tricky wording. Everyone feels this way.

Students scoring 240+ feel uncertain. Students who barely pass feel uncertain. The feeling after the exam does not predict your score.

I've had students walk out saying "I definitely failed" who passed comfortably.

I've had students walk out feeling confident who scored lower than expected.

Your post-exam feeling is not data. Wait for the actual result.
