Dear aspirant,
As you have secured 420 marks in inter board and 100 marks in eamcet so let me tell you that the prediction of your rank is very difficult because it depends on certain factors like number of candidates appearing in the examination, number of vacant seats in college, previous years cut offs and difficulty level of the paper.
So, i would recommend you to take help of the previous year cut off but it will also vary because the dynamics gets changed.
