I hope this information will help you.

The best college or institute in Bangalore to study Aeronautical Engineering is without doubt Institute of Science. You must attempt to get admission in this very famous landmark of Bangalore. Best wishes to you.

Yes, you can pursue after B.Sc it from Sikkim Manipal University.

You should be in the top 1000 in Second paper of JEE, and then only you are able to take admission in IT.

You will need to check the information with the college where you wish to apply for. Changing college with the same course shouldn't be a problem as far as colleges within the same university are concerned. But, I am not very sure about course change from one country to another. So, would suggest you to get in touch with the university where you wish to admission in.

Yes, you can apply to Christ College for Masters if you have at least 50% aggregate in your Bachelor's.
Regards.

Dear Hartej,
BIT is a good college with good placements record as it is one among the oldest Engineering College in Karnataka. Google only visits IITs these days so BIT will have other top MNCs coming for placements.
