Relax, a slight difference in your name between marksheet and Aadhaar card won't make much of a difference.

Most places, be it institutions or organizations, understand that people write their names differently, especially in India. So long as the two are connected and recognizable, no problem arises.

Here are a few steps you may consider when making it smooth:

Contact Appropriate Institution: Contact the respective college, university or even organization by which you are applying. Explain the discrepancy and attach a family affidavit or even a name change affidavit.

Supporting Documents: Prepare any such documents that can support your identity such as birth certificate, PAN card or any official document.

Be Honest and Transparent: Give full disclosure concerning the dispute on the name upon verification. Explain the matter as calmly as you can and offer any documentation that might be required.

Many such minor disputes can therefore be resolved if adequate documentation coupled with adequate explanation are provided.

However, in case you encounter major problems or bottle necks, it would always be beneficial for you to consult a legal advisor or involve the right authorities for assistance.
