You can opt to enroll in BITS, Goa for Chemical Engineering only if you are positive to pursue your career in that field, or if you are simultaneously planning for any in-depth research activities in chemical engineering-related fields in the upcoming years.
However, the older IIITs are comparatively better in terms of providing the best of everything, than it is in the newer ones. But, if you are personally considering the branch, then CSE has always been ahead of the list in terms of placement opportunities as opposed to Chemical.
