what about the ingrated course on mathematics

Dear aspirant,

There is an integrated program of 5 years in engineering colleges and IISER institutes as well for mathematics. There are several NITs and IITs where it is taught as an integrated course .

This program is for 5 years. Here you'll have to study the engineering version of mathematics. For NITs and IITs and other engineering colleges the joining procedure is done through JEE mains and JEE advance rank.

While for IISER there's a different exam conducted for all IISER institutes only, to get an admission there you'll have to score well there.

Hope this helps!
