Hello!!

Hope you are doing great!!

As you mentioned your rank, it is very difficult to estimate the score or marks based on the rank as it varies from year to year, and difficulty of the question paper and also total number of candidates attempted for the examination.

For the rank of around 4500  , your approximate score will be around 90-95 marks.Let me tell you that as per the previous year cutoff's you have less chances of getting seat in CSE branch,but also remember that it is based upon the cutoff's .
