Hello,

91.8 percentage is enough to get admission in any engineering college , you need to clear JEE mains with enough marks or you need to clear the cutoff of GUJCET for taking admission in DAIICT .

It would be difficult to tell you exactly about the rank required for admission to DAIICT as the cutoff varies every year depending on various factors. However, you can go through the link below and check the previous year allotment list for reference

Good Luck!
