Hey there. 

As per your query I would like to tell you that according to your question. If you are from general category it is safe if you secure ranks between 120-150 in the final merit list, if you are from reserved category then it goes upto 360ranks. 

As per year, the cuttoff marks varies depending upon the number of students appearing in the exam and the difficulty level of exam papers in the Exam. 

Hopefully it's will be useful to you. 

GOOD LUCK..
