Hi,
Aeronautical engineering is a upcoming field and there are limited opportunities available for students in private sector.  For who clear gate exam with valid score can get plenty of opportunities in government sector such as DRDO, HALetc. To become a successful aeronautical engineer,  it depends on knowledge and expertise of students irrespective of college your are applying or studying.  Try to first clear your school basics and so that it will help you to understand your college subject easily . From second year you can start preparing for gate exam,  by the start of 4th year.  You can prepare well side by side along with your college subject.  Then you can easily crack gate.
