Hi Srijan! 

Greetings! 

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

With 220/400 your score out of 65 is around 35.75.

And with 84% in class 12, your score is around 29.40 

So your composite score is around 65.15/100.

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 63.52 had an AIR 1282;
2. Candidate with CS 65.32 had an AIR 965;
3. Candidate with CS 65.12 had an AIR 1002: and
4. Candidate with CS 65.78 had an AIR 901.

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.

So with this score i guess  you can get into the third best college for BMS that is DDUC.

Only after the result is out and cut off declared will you be able to know if you would get a college of your choice or not. 

Please upvote if this was helpful to you. 

Thank you and good luck.
