You’ve put in the hours — labs, practice exams, and the inevitable 2 a.m. debugging session. Now the last 24 hours aren’t about learning more; they’re about protecting your performance. This playbook keeps you calm, prepared, and focused on the only thing that matters: executing on exam day.
The 24-Hour Countdown: What to Do (and Not Do)
T-24 to T-12: The Final Review Window
Stop trying to cover new topics. Instead, do a targeted review of your weakest areas — but only if you can do it without spiraling. A quick skim of your notes on SageMaker built-in algorithms, model tuning, and ML pipeline patterns is enough.
- Review your own cheat sheet (if you made one) — not someone else’s.
- Re-read the official exam guide’s “content domains” section once.
- Avoid full-length practice exams now. A low score will only shake your confidence.
T-12 to T-8: Physical Prep
Your brain runs on glucose and sleep. Treat it that way.
- Eat a balanced meal — not a heavy one. Think rice, dal, and a vegetable curry, not a deep-fried feast.
- Pack your bag tonight. Don’t leave it to morning.
- Set two alarms (one backup).
- Plan your commute with a 30-minute buffer for traffic or transit delays.
T-8 to T-1: Sleep and Morning Routine
Aim for 7–8 hours of sleep. If you can’t sleep, don’t panic — lying still with your eyes closed is still rest. In the morning:
- Wake up at least 2.5 hours before the exam.
- Eat a light breakfast: eggs, toast, fruit. Avoid anything too sugary or greasy.
- Do a 10-minute walk or light stretching. No high-intensity workouts.
- Review a single page of high-yield formulas (e.g., evaluation metrics, bias-variance tradeoff) — just to warm up, not to cram.
What to Carry (and What to Leave Behind)
For a Testing Center (if you chose in-person)
- Valid government-issued photo ID — passport, driver’s license, or Aadhaar. The name must exactly match your exam registration.
- Confirmation email — either printed or on your phone (but check the center’s policy on phones).
- Water bottle — clear, no label. Some centers allow it; others don’t. Check in advance.
- A light jacket or sweater — testing rooms are often cold.
For an Online Proctored Exam
- Your laptop charger — don’t rely on battery.
- A quiet, closed room with no other people (proctors check).
- A clean desk — remove all books, papers, phones, and smartwatches.
- Your ID — you’ll show it to the proctor via webcam.
Leave behind: your phone, smartwatch, and any notes. Even a glance at your phone can get your exam flagged.

In-Exam Pacing: The 3-Hour Strategy
You have 180 minutes for 65 questions. That’s about 2 minutes 45 seconds per question. But not all questions are equal — some are long scenario-based ones, others are short fact-checks.
The First Pass: Answer What You Know (0–90 minutes)
- Skim each question. If you know the answer, mark it and move on.
- For questions that seem complex, eliminate obviously wrong options, then move on. Don’t get stuck.
- Use the “flag for review” feature liberally — but only for questions you’ve partially narrowed down.
The Second Pass: Tackle the Flagged Ones (90–150 minutes)
- For each flagged question, spend up to 3 minutes. If you’re still unsure, pick your best guess and move on.
- Remember: there’s no negative marking. An unanswered question is always wrong.
The Final 30 Minutes: Review and Guess
- If you have time, review all flagged questions again — but don’t change answers unless you have a clear reason.
- For any remaining blanks, guess. A 25% chance is better than zero.
- Check that you’ve answered every question before submitting.
Common Exam-Day Pitfalls (and How to Avoid Them)
- Overthinking the scenario length: Long questions often have the answer hidden in the last line. Read the question stem first, then the details.
- Misreading “which is NOT” or “which is LEAST”: Circle these words mentally. They flip the entire question.
- Spending too long on one question: If you’re past 3 minutes, you’re losing time for easier ones.
- Ignoring the time check: The exam timer is visible. Glance at it every 10–15 questions.
What About the Exam Format?
- The exam is multiple-choice and multiple-response. For multiple-response, the prompt tells you exactly how many options to select (e.g., “Select TWO”).
- You can take a break, but the timer keeps running. Only take one if you truly need it.
- The exam is adaptive? No — it’s not. The difficulty is fixed per exam, but your performance doesn’t change the questions. So don’t panic if a question feels hard; it’s just one data point.
