If you have made a mistake in the gender section of your NTA ICAR JRF application form and the correction window has already closed, here are the steps you can take:

1. Contact NTA Helpdesk : The first and most important step is to contact the National Testing Agency (NTA) helpdesk directly. You can do this via email or phone. Provide them with your application number, the mistake in your form, and a request to correct the error. Be polite and concise in your communication.

2. Email Communication : If you choose to email, write a formal email explaining the mistake and attach any supporting documents (like your ID proof) that confirm your correct gender. Make sure to include all relevant details such as your name, application number, and the exam name.

3. Visit NTA Office (if feasible) : If you're in close proximity to the NTA office, consider visiting in person to resolve the issue. Bringing a printed copy of your application form, a government-issued ID, and a written request for correction could expedite the process.

4. Document Everything : Keep records of all communications with the NTA. This will be helpful if the issue isn't resolved quickly or if you need to escalate the matter later.

While NTA typically adheres to its correction window deadlines, they might consider corrections for significant errors, especially if contacted promptly.

hope this helps you!!
