Dear Harsh,
If it would not have been an important subject than why would CBSE had introduced it into its curriculum? It is a subject that will give you a better understanding of programming and other technical knowhow that you will require in your graduation to better understand the subject. It will work as a foundation for future. So don't distract yourself by what people say. Just focus on your studies and go ahead in life.

Hello Pranjal,
First and most importantly just don't worry. You have chosen the best branch. Humanities have great potential ahead. There is so much variety of courses available, you can't even imagine.
Presently, just concentrate on scoring good marks in 11th and 12th.

In mathematics, integration and derivation and geometric section are the most important in civil engineering. In physics, a measurement is the most important topics in civil engineering. In chemistry, properties of solid elements are the most important topics for civil engineering.

Hi Indal,
If you want to go for IIT then you will have to give IIT-JEE entrance examination in which you will have to score at-least 300 above out of 360 (JEE Mains) or 366 (JEE Advanced) to get a good college like IIT Mumbai. Further, you have to score at-least 75% in class 12th for being eligible for admission. So, start your preparations from now. Join a good coaching for your preparations. Hope your dream comes true. All the best.
