Engineering Scope

I think mechatronics is the most demanding. Do not follow my suggestion blindly, you should wait for another answer.

Your ability and willingness help you to get success in life. Canada is one of the best place for electrical engineers and Canada also need many skillful workers for their growing economy, so don't worry, if you have completed your study in Canada, you can earn Rs.2.5 lakhs to Rs.4 lakhs in a month.
All the best.

As per the last year economic data of Canada government, they need people in civil engineering sector, chemical engineering sector, Oil and gas sector, petroleum sector, renewable energy sector and environmental sector mainly. But, engineers in various sectors are also welcome and also have good prospect.

Both the branches have great prospects in Karnataka, and in India too.

India produces very large number of engineering graduates. Engineering degree from good colleges will help you to have good career. If you do B.Tech from a lower rank engineering college, then you will have to pursue MBA or M.Tech for a meaningful career.

The current scenario is such that grades won't matter much. Yes, a score above 70 will open doors for getting good opportuniies and same goes for placements after BE. They aren't too much dependent on grades (but you should have decent one anything above 70 is good). The only thing that matters is the skills you acquire with the got number of opportunities.

Eligibility for GATE examination is a B.Tech/BE/AMIE or M.Sc. After 12th you can appear for JEE.

Eligibility is a Bachelors degree in Engineering/Technology (4 years after 10+2 or 3 years after B.Sc./Diploma in Engineering/ Technology) and those who are in the final year of such programs.
