​how many tier in ssc cgl?​

Correct option is A

​SSC CGL has a total of two main tiers — Tier 1 and Tier 2. Tier 1 is the first exam that includes basic questions from Maths, English, Reasoning, and General Knowledge. Once you pass that, you go to Tier 2, which is more detailed and post-specific. Tier 2 has multiple papers, depending on which job you're aiming for. After clearing both tiers, there’s a Document Verification round. Earlier, there were four tiers, but now it’s simplified to make it easier for candidates.​
