Unfortunately, with a score of 127 in NEET, securing a seat in a government Siddha medical college in Chennai is highly unlikely.

The cut-off marks for government medical colleges, including Siddha, are significantly higher. Even with the EWS category, such a low score would not be sufficient for admission.

It's recommended to explore other options like private colleges or different courses based on your interests and career goals.

Remember to keep working hard and don't feel disappointed.
