JEE

Every engineering stream now a days have at least one programming language. So, you can't run away from it. I think you don't need to fear about programming language. It is easy than other subject. You first decide whether which branch you more interested and don't think about other thing.

All engineering exam required 60% in class 12th with PCM subjects.

For IIT – Kanpur, you have to appear and qualify the IIT JEE exams.

Hello,
Those students who have passed their class 12th in the year of 2015 or 2016 are eligible to appear for JEE mains 2017. As you have passed your class 12th in the year of 2012, I am afraid you are not eligible.

Can I know about the course?

Hi,
Chemistry -
Study organic and inorganic chemistry as much as you can. Physical chemistry questions are easy too but you can do well without them.
Mathematics-
1. Complete calculus. Mostly questions on limits and differential eqns. are very easy. Integration depends on you.
2. Simple but scoring topic

Yes, you can and it is nice that you are not getting into rush.

Yes, you can get admission in IIIT's through JEE mains only and from next year, class 12th percentage will not be given weightage. You just need to score minimum 75% in class 12th to be eligible for JEE mains.

The qualifying score is 55 marks. If you want to get any government college, then above 120 marks will fetch you that college.
