Common Mistakes to Avoid
- Do not wait until exam day — the download link closes on 24.09.2026, the same day the CBT is scheduled.
- Carrying only the original photo ID and forgetting its photocopy — both are required and must be handed in together with the call letter.
- Bringing a Ration Card or Learner’s Driving License as ID proof — neither is accepted for this exam.
- Appearing with mehndi, stamp ink or coating on the fingers, which can fail the biometric thumb impression and cause non-admittance.
- Wearing shoes, socks or clothes with metal zippers and big buttons, which slows down frisking and risks missing the reporting time.
- Pressing a keyboard key after the exam begins — this locks the exam, and you cannot finally submit before the full 150 minutes are over.
