Candidates who clear Tier-1 move to the Tier-2 exam.
Paper-1 of Tier-2 is compulsory for all posts and includes a data entry speed test.
Other Tier-2 papers apply only to specific posts like JSO.
After Tier-2 come document verification and the medical examination.
The final merit is based on Tier-2 marks, with category-wise cut-offs.
Always check the official notification for the current exam scheme.
