Hi Pradiba, 

The eligibility  for applying for TNAU are as follows:

Any student who studied one of the following groups in higher secondary (+2) are eligible

     - maths, physics, chemistry,  biology ( OR )

     - physics, chemistry, biology with one of the following subjects as fourth subject. 

( chemistry,  biotechnology, microbiology, home science,  computer science) 

Since you have done MPC with IP,  I am sorry to say that you will not be eligible  to apply for TNAU.  

Hope the information was helpful 

All the best!
