Engineering

Hello Kamlesh Patil,
Firstly, you must decide whether you want to join IAF as pilot or engineering officer. Even if you become pilot, you cannot become a commercial pilot. I am attaching a link that will give you all the required information about different aspects and the means through which one can join IAF as an officer. Even though information pertains to 2018, you can extrapolate it to 2019 or 2020.

Hi,
You can refer to this link for the list of colleges:

Marine engineers and naval architects earned a median annual salary of $93,350 in 2016, according to the U. S. Bureau of Labor Statistics. On the low end, marine engineers and naval architects earned a 25th percentile salary of $72,600, meaning 75 percent earned more than this amount.

For B.Tech in civil engineering, you need to have passed 10+2 with PCM (physics, chemistry and mathematics) is the basic requirement to take admission in B.Tech civil engineering programme.
Percentage required in qualifying exam is 50% for most of the engineering institutes. However, required percentage criteria depend on college. Diploma holders in the mechanical or allied stream are also eligible to take admission, in the second year of the course. They must have done their Diploma after10th.

No, it is not possible. For admission in 2nd-year of engineering you must have a B.Sc degree.

To me, agricultural engineering is a better option than doing B.Pharma. Especially, in an agrarian country like India, agricultural engineering degree holders are in demand and after your B.Tech programme in this branch, I am sure you will get good job offers.
