According to your percentile your rank is near 104630. You can also predict your rank using the Rank Predictor Tool .

NIRMA Institute of Technology :

• It takes admission on JEE-Main basis as well as GUJCET basis, which means that you have two ways to get admission to this college.

I think you have gone through the given data, now you can choose what is most appropriate for you.

According to me you should not leave the hope to get IITs because you have one attempt remaining of April, 2020 and your hard work can take you beyond your thinking and expectations.

All the Best !!
