1) The basic eligibility criteria for BE / B.Tech program is 10+2 Science (physics, chemistry and maths) with a fairly high percentage of marks in the aggregate.
2) One must pass the qualifying exam I.e. IIT JEE for admission into Indian Institutes of Technology (IITs).
3) For M.Tech program in aeronautical engineering one should have completed degree in (BE/B.Tech) aeronautical engineering or any other equivalent branches of engineering.

Yes, you are eligible for admission in PEC.
PEC conducts a test every year to take admission in that college.
Hurry up, you have to visit PEC for admission.

Hello Venkatesh,
After completing Diploma, one can get lateral admission in the 2nd year of engineering or use Diploma as equivalent to class 12th and get admission in the 1st year. Now, if the Diploma is in mechanical, then for lateral entry there will be restriction as to which branch you can get admitted. However, if you are using Diploma as equivalent to class 12th, then you can get admission in any branch of engineering.

Hello Rajesh,
Indian Aerospace and Engineering is an institute, which is actually not an engineering college, but an institute that trains in aircraft maintenance that is approved by DGCA.

Hello Basavara,
Admissions to NIT's is through JEE Mains. Admissions to IIT's is through JEE Advanced. For Advanced, one has to go through Mains. For colleges in states, one has to go via CET.

Hello Hitesh,
I think you are not eligible because you are beyond the acceptable window for passing of 12th. What made you wait for almost 4 years? Now, you can attempt Engineering via AMIE.

Hello Janani,
Admissions in TN are governed by eligibility rules link for which I am attaching. Robotics is a challenging field. Aerospace has perhaps limited job opportunities in India.
