Dear aspirant,

It is not mark which gives you chances of getting into IIT but the rank. the rank depends upon the difficulty of exam and if the exam was difficult than your marks would be sufficient to get into IIT and you might even get a chance to interview in some PSU however if the exam was easy or moderate then the chances are that you will not be able to get into IIT.

This year the paper was moderate and hence the chances of you getting into IIT are medium.

Hope this helps. Thanks.
