With a 94.43 percentile and an EWS rank of 11,878 in JEE Mains, your son has a fair chance of getting admission to HBUT Kanpur in B.Tech Electronics and Communication. It depends on the competition and the number of seats available. Electronics and Communication is a popular branch, so the cutoff might be a bit high. Still, with his rank and percentile, he should apply and participate in counselling. It’s good to keep some backup options too, just in case.
