Hi ! Well I will suggest you then biotechnology if your target is ms in USA, then chemical engineering if target MBA and for placement then go for civil. This is what I suggest you. Well there is a reason behind it. Biotechnology is the most best branch to go outside for its demand is high in abroad due to companies like nestle, and being pasteurised areas. Now, chemical is not at all a headache stream and you can easily prepare for MBA. And placement wise civil is better from all of them. And in case of IIT, it is IIT Jodhpur, IIT Patna, IIT Guwahati, IIT Jammu, IIT Mandi and IIT Tiruchirapalli and other newer and third-tier IIT's. So hope you understand and best of luck to you.
