Hello aspirant,

The process for getting admission to NIOS for an additional subject can vary slightly depending on whether you're already enrolled in the NIOS system or not. However, the general steps are as follows:

If you're already enrolled in NIOS:

1. Visit the official NIOS website: Go to the NIOS admission portal and log in using your existing credentials.
2. Choose the additional subject: Select the subject you want to add from the available options.
3. Fill in the application form: Provide the necessary details and submit the form.
4. Pay the fees: Pay the required fees for the additional subject.
5. Submit the application: Once you've completed the previous steps, submit your application.

If you're not enrolled in NIOS:

1. Visit the official NIOS website: Go to the NIOS admission portal.
2. Choose the additional subject: Select the subject you want to add from the available options.
3. Fill in the application form: Provide the necessary details, including your previous academic qualifications.
4. Submit the application: Once you've completed the previous steps, submit your application.
5. Wait for the admission confirmation: NIOS will review your application and inform you about the admission status.

Regarding your specific question about the admission site showing that you've already taken admission or fees are pending:

This could be due to a few reasons:

• Previous admission: If you've previously taken admission to NIOS, even if you've dropped out or completed your course, the system might still show your previous admission details.
• Pending fees: If you've previously taken admission but have pending fees, the system will show that you have outstanding dues.
• Technical issue: There could be a temporary technical issue with the admission site.
  
  I hope this information helps.
