The Staff Selection Commission (SSC) is set to publish the provisional answer key for the CGL Tier 1 Examination 2025 on October 15, 2025, on its official website. Alongside this, the response sheets and question papers will also be made available to candidates. 

Once out, aspirants can raise objections against any discrepancies in the answer key within a two- to three-day window, for which a prescribed fee per question must be submitted. Objections will be reviewed by subject experts before the final answer key is released. 

To access the documents and submit objections, candidates must log in using their credentials (registration ID / roll number and password) on the SSC portal. After objections are evaluated, SSC will publish the final key and proceed with result declaration based on that. 

This process ensures transparency and gives candidates a chance to challenge errors, helping maintain fairness in the evaluation process.
