Reviews

What candidates say after passing

★★★★★
GlideRecord is the foundational server-side scripting API and the exam tests it at depth.Edureify AI's database operation scenarios - query, insert, update, delete - with and without sharing context built the GlideRecord fluency the exam requires rather than just surface familiarity.
Sofia R.
Scrum Master
★★★★★
The client-side vs. server-side distinction is the developer's most important architectural decision.Edureify AI's UI Policy vs. Business Rule scenarios - same outcome, different execution context - made the appropriate choice instinctive based on where the logic needs to run.
Hugo D.
Enterprise Architect
★★★★★
Update Set discipline is as important for developers as for administrators.Edureify AI's change transport scenarios required me to capture every customization before making it - building the habit that protects production instances from ungoverned development changes.
Chris H.
Solutions Architect
★★★★★
Application scoping was the concept that changed how I think about ServiceNow development.Edureify AI's scope isolation scenarios showed the downstream problems that global scope development causes - collisions, upgrade risks, support complexity. Scoped development isn't a recommendation, it's a requirement.
