Hello shiva,

The admission in ipu are based on your rank only which is calculated by the marks you have scored but the result is declared after the calculation of rank and the rank is only mentioned so there is no role of marks.

After the declaration of results, register yourself for counsellings session so you can get to the colleges as per your rank.

I hope this helps you out. If there is anything else that I can help you with, then please let me know.
Till then, all the very best. Stay home and stay safe.
