❓ Frequently Asked Questions (SSC CGL Tier 1)
Is there a sectional cutoff in SSC CGL Tier 1?
No. There is no sectional cutoff in SSC CGL Tier 1. Qualification for Tier 2 is determined purely by your aggregate normalized score across all four sections (out of 200 marks).
Does Tier 1 score count towards the final merit list?
Under the revised SSC CGL scheme, Tier 1 is qualifying in nature. While your Tier 1 score determines whether you qualify to write Tier 2, the final merit ranking and department allocation are based solely on your Tier 2 performance.
Where can I take authentic full-length SSC CGL Tier 1 mock tests for free?
MockTestVault provides 100% free, distraction-free computer-based mock tests on mocktestvault.com/ssc-cgl/ with full 100-question timed simulations (Mocks 01, 02, and 03), 12 sectional speed drills, TCS iON palette navigation, and instant solutions.
