Lakshmi, please do not be swayed by uninformed opinions that chemical engineering is not for girls. If you love chemistry and math, chemical engineering is a very good career option for you. I grew up in India myself and went through the JEE system a while ago, and studied chemical engineering. And as a woman, I have had and continue to have a very rewarding career as a chemical engineer. I teach and conduct research at a University in the US, and about 30-40% of our chemical engineering students (out of a total of 700) are women. Most of our students, both men and women, go into industry and have vibrant careers. So there is no real rationale or basis behind the statement that chemical engineering is not for girls.
