JEE Main Response Sheet is the answer sheet of the candidate that they submitted during the Examination. Basically, when the candidate apears in the examination they appear in the exam online. All these answers are saved as recorded during the test. Finally, NTA accumulates these answers and arranges them in a PDF format for the candidates. This is known as the Response Sheet. Candidates need this response sheet to cross reference their answers they check in the JEE Main Answer Key. The response sheet will release on 23rd April 2019 along with the provisional answer key on the official website of National Testing Agency.
