IIT Kanpur - Indian Institute of Technology

Both the IITs are good but in my opinion, IIT Delhi is better than IIT Kanpur because IIT Delhi provides good infrastructure and good course curriculum.

Yes, you can but I'll suggest you to go for M.Tech instead of M.Sc physics at IIT Kanpur.

If you consider long-term career opportunities, IITs provide wonderful opportunities for PhD.Also, some research schools in Europe and certain universities abroad hire IIT M.Sc students for a Ph.D position based on interviews and GPA(sometimes, research experience plays a more important role).

I will advice you to first sort your branch preference. For example you want to take civil branch , next question arises which IIT, so then you can visit website and check your their respective placement statistics. This way u will get clear insight.

Hello Abhishek, IIT K is the second best choice of students after IIT Bombay. I feel one must be in top 150 to get shot at admission in IT branch in IIT K.

First of all, congratulations brother!
Of course yes. You will get aerospace in any one of the IITs you want because your marks are damn good in Advanced.

Hello, hope you are doing well.
Sorry, but you don't have a chance to get any of the core branches in IIT Kanpur including biological and bioengineering, chemical engineering, chemistry, civil engineering, economics, material science and technology.

No you cannot get admission in IIT by clearing UPTU Exam.

Hello Prince, it's very nice to hear that you have already fixed the aim of becoming an engineer. As a first step, you need to study really well for next two years with understanding the subject being the theme. Must score at least 75% in 12th and thereafter can apply for B.Tech programme in a reputed college.
