Hello,

your son's rank doesn't depend on your category but it alone depends on the score you get in the EAMCET exam.

comparing the previous years trends your rank would be in between 5000 to 10000

Your rank cannot be predicted very precisely because of change in trends every year i.e every year the number of students applying for the exam may be different and students who score marks more than or greater than yours will be different.

You can predict your rank and college from the careers 360 predictor  from the following link.
