If your admit card says **iON Digital Zone**, this guide is for you. Most computer-based tests (CBT) in Patna — SSC, Railway, banking and many state exams — run at TCS iON Digital Zone centres. Candidates lose time on exam morning because two centres have similar names or the venue is a lane inside a colony. Verify your exact centre tonight, not at the gate.
Exam days coming up

Exam-morning basics
1. **Match the full centre name and gate** on your admit card with the centre page — similar names are the #1 cause of wrong-centre panic. 2. **Search your exact centre on [Margdarshak](/)** for the map pin, locality and directions. 3. **Reach 90 minutes early** for CBT frisking and biometric queues. 4. Travelling with others? Open an [Exam Day Command Room](/exam-day-command-room) to share rides and live updates. 5. Keep [Safety SOS](/sos) set up if family wants to track your journey.
All the best — verify tonight, travel calm tomorrow.
