Understanding the Issue: Subject mapping errors can be a significant obstacle in the admission process. If your DU CSAS application has been rejected due to this reason, it's crucial to take immediate action.

Steps to Take:

1. Contact the College Directly: Reach out to the admissions office of the college where you were allotted a seat. Explain the situation clearly and provide evidence of the correct subject mapping.
2. Request a Review: Ask the college to review your application and reconsider your admission. Provide any necessary documentation to support your claim.
3. Explore Other Options: If the college is unable to rectify the error, consider exploring other options within DU. There might be other colleges or courses that align with your preferences and meet your eligibility criteria.
4. Consult with DU's Centralized Admission Cell (CAC): Contact the DU CAC for further assistance. They may be able to provide guidance or intervene on your behalf.
5. Consider Appealing: If the college or CAC is unable to resolve the issue, you may have the option to appeal the rejection decision. Check the DU admission guidelines for specific appeal procedures.

Additional Tips:

• Be Persistent: Follow up regularly with the college and CAC to ensure that your application is being addressed promptly.
• Provide Clear Evidence: Gather all relevant documents, such as your mark sheets and course descriptions, to support your claim of correct subject mapping.
• Explore Alternative Options: If the situation is not resolved in your favor, consider exploring other universities or colleges that may be suitable for your academic goals.

By taking these steps and being proactive, you can increase your chances of resolving the issue and securing admission to your desired course at DU.
