It is better not to target a branch change because good branches are available only if you have an 8.5+ CGPA (which varies based on the vacancies).
When it comes to Chemical Engineering, this branch opens up a plethora of opportunities. But you need to work hard and score a decent CGPA. Many recruiters opt for students with a good CGPA and practical knowledge.
