Hey Aspirant,

The rank list will be prepared on the basis of the combined marks secured in AP EAMCET  and in Intermediate. The weightage is divided into ratio of 75:25 i,e 75% weightage in the entrance exam and 25% weightage to the marks obtained in IPE i.e in Physics,Chemistry and Mathematics(including practical's)of class 12th.

So,Firstly you have to know your AP EAMCET marks and also your 10+2 marks. The other thing is even if you have your marks with you we can't estimate the rank because many people appear for exam and different for every year .so  if you have maximum score you will definitely  be the one among top rankers,

Hope this information helps you!

GOOD LUCK!
