2019 NIRMA University cutoffs are not exactly known so I'll guide you with the 2018 cutoffs. And before that let me tell you cutoff marks keep varying or fluctuating from year to year as they depend on various factors like number of candidates appearing and also the paper level difficulty, etc. So I'll better guide you with the ranks. So in 2018, the cutoff for NIRMA University Computer Science branch was AIQ rank of 23293. For IT, it was around 36421 AIQ rank. To get this rank you need around 160+ marks in your Jee mains exam to be on the safer side.
