Hello. Can you please tell me your board marks?  without that i can not make any suggestions. However The cut-off is based on different factors which are given below:

Exam difficulty level. 
Number of students appeared for the exam. 
Availability of seats in colleges. 
Number of students qualified the exam. 
It's also very category wise.. 
But going to previous year rank list last rank of first counselling for General category is 477.Please tell me your category and board marks so I can be precise. All the best.
