Hi Sudhanshu! 

Greetings! 

The composite score is based on 35% class 12 best of 4 and 65% DU entrance exam score.

With 293/400 your score out of 65 is around 47.61.

And with 83% in class 12, your score is around 29.05 .

So your composite score is around 76.66/100.

On the basis of this score, rank will be allotted and colleges as well.

However, referring strictly to last year’s data, this is what I found -

1. Candidate with CS 76.49 had an AIR 54;
2. Candidate with CS 76.03 had an AIR 64;
3. Candidate with CS 76.25 had an AIR 57; and
4. Candidate with CS 76.51   had an AIR 53;

From the aforementioned data you could estimate what your All India Rank should be, assuming the overall performance pattern of the students remains similar in this and last year.

Thank you and good luck .
