Yes you can get chemical engineering seat at sastra University for your marks and percentile on regular biass but with the change in trends I cannot be sure about your seat because there may be more students ce5 scored more marks in the IP exam compared to you and having more percentile in JEE mains still you can confirm your seat in chemical engineering at sastra University by attempting the sastra University entrance exam.

But on general bass I would say that for 974 marks in IPE you can get a chemical engineering seat at sastra University
