Exam Day Tips and Strategies

Before the Exam

• Test your equipment: If taking the online proctored exam, verify your webcam, microphone, and internet connection work properly
• Check system requirements: Ensure your computer meets Kryterion’s technical requirements
• Prepare your environment: Choose a quiet, well-lit room free from interruptions
• Have identification ready: Government-issued photo ID is required
• Clear your workspace: Remove all unauthorized materials from your desk
• Get proper rest: Avoid last-minute cramming the night before

During the Exam

• Read questions carefully: Pay attention to keywords like “BEST,” “FIRST,” “ALL,” or “EXCEPT”
• Watch for multiple-select questions: These require you to select all correct answers—partial credit is not awarded
• Manage your time: With 60 questions in 90 minutes, aim for about 90 seconds per question
• Flag uncertain questions: Mark questions you’re unsure about and return to them later
• Don’t overthink: Your first instinct is often correct; only change answers if you have a clear reason
• Eliminate obviously wrong answers: This improves your odds on difficult questions

Technical Tips

• Know the Glide APIs: GlideRecord, GlideSystem, GlideForm, and GlideAjax methods appear frequently
• Understand script execution order: Know when Client Scripts vs. Business Rules execute
• Remember ACL evaluation order: Table → Field → Row-level (deny stops evaluation)
• Know when to use what: UI Policies vs. Client Scripts, Business Rules vs. Script Includes

Common Mistakes to Avoid

Mistake 1: Relying Solely on Theoretical Knowledge

Problem: Many candidates study documentation and courses but skip hands-on practice, leading to difficulty applying concepts in scenario-based questions.

Solution: Dedicate at least 50% of your study time to hands-on practice in your PDI. Build applications, write scripts, create workflows, and implement security—don’t just read about them.

Mistake 2: Neglecting Domain Balance

Problem: Candidates often focus on their strongest areas while neglecting weaker domains. Since you must pass each section, this strategy backfires.

Solution: Track your practice exam scores by domain and allocate more study time to lower-performing areas. Every domain matters equally for passing.

Mistake 3: Underestimating Scripting Complexity

Problem: Some candidates have limited JavaScript experience and struggle with scripting questions that make up a significant portion of the exam.

Solution: Strengthen your JavaScript fundamentals and practice writing ServiceNow-specific scripts. Learn the Glide APIs thoroughly and understand when to use client-side versus server-side scripting.

Mistake 4: Ignoring Recent Platform Updates

Problem: The CAD exam is updated to reflect new platform releases (like Zurich/Yokohama). Outdated study materials may not cover new features.

Solution: Check the official exam blueprint regularly and review release notes for new features. Pay special attention to Now Assist for App Engine, Flow Debugger, and other recent additions.

Mistake 5: Poor Time Management on Exam Day

Problem: Spending too much time on difficult questions early in the exam leaves insufficient time for easier questions later.

Solution: If a question takes more than two minutes, flag it and move on. Complete all questions you’re confident about first, then return to flagged questions with remaining time.
