The National Testing Agency (NTA) has revised the provisional answer key for the Joint Entrance Exam (JEE) Main 2026 Session 2, correcting 19 errors in the Chemistry section following student complaints. After the initial answer key was released on April 11, candidates expressed concerns over discrepancies, prompting the NTA to review the answers. In a statement, the agency acknowledged the issues and advised candidates not to pay challenge fees until further clarification was provided. The updated answer key is now available on the official JEE Main website, where candidates can log in to check their responses and raise objections if necessary. The challenge window is open until April 13, 2026, with a ₹200 fee per question. The final answer key will be binding for result preparation, expected by April 20, 2026. This revision is a significant relief for students who had raised concerns about the accuracy of the exam process.
