Hello Aspirant

Yes, you can definitely pursue MBBS in Tamil Nadu or Karnataka after completing your 11th and 12th there.

Here's a breakdown of the process:

Ensure you have completed your 11th and 12th standard with the required subjects (Physics, Chemistry, Biology, and English) from a recognized board in Tamil Nadu.

Since you've studied in Tamil Nadu, you'll be eligible to appear for the NEET (National Eligibility cum Entrance Test) exam. NEET is the common entrance exam for medical admission in India. Both Tamil Nadu and Karnataka have state quotas for medical admissions, which can increase your chances of securing a seat if you belong to the respective state.

Hope this helps
