Hi Rohit,

             See, maths is necessery in engineering. It's mandatory for all engineering students to complete 4 maths papers. But if you're talking about chemistry, then you should go for chemical engineering or bio-technology. Beside that you can think about food processing, metallurgy, plastic and ceramic, leather technology. This branches are not available in many colleges so choose wisely. I can suggest you Jadavpur University where most of the branches are available. Don't forget to go through MHRD ranking of colleges and check their records before taking any decision.

Warm Regards
