Hi

NIOS( National institute of open schooling) is government approved institution for students.

For eligibility in NEET, student must have an aggregate of 50 percent in PCB for general category and 40 percent aggregate for SC/ST category.

In Tamilnadu, there has been news to remove NIOS students from NEET but there is no confirm news. These students will definitely get a chance to be be able to get admission in any medical college of their respective state.

So yes, if you get enough marks for government medical college in Tamilnadu, you will get your desired college.

Best of luck
