B.Tech

Hi,
B.Tech is a 4 years course in India.

In order to get a job in ISRO, B.Tech in CSE, ECE and Mechanical are some preferred branches. After B.Tech, you have to clear GATE examination with very good marks and then you have to clear ISRO entrance interview.

Yes, surely, this helps but it depends upon the official authorities.

For that, you have to opt CS branch and then you have to gain specialisation in hacking. After that, you can become a ethical hacker.

See, if you are interested in both. Then, it will cause a problem for you. I'll prefer you to go and discuss each and every aspect with your elders and the person who is in this field, which your are confused in. As far as I have seen opting for the GATE is better for you as there is job security for you.

In spot round of counselling, you will only get the college of your choice that you have filled at the time of registration and from that, if your eligible in that choices, then you will be granted one of the college.

If you want, you can participate in that counselling but look, counselling rules and all the instructions carefully.

You can opt for many courses if you want. You can also have specialisation in this subject too. Otherwise, you can also go abroad and then do higher studies in any of the subject in which you can have better future.

PGDM in Banking and Finance would be good for you. Because it is in your field and will boost your CV.
