If you are applying for colleges in Canada through GMAT, work experience is mandatory. You cannot give GMAT without any work experience.

Yes, it is recognized and valid.

Can you mention the program name you want to apply for?

As I have applied last year with a CGPA of 6.5, which is almost equal to you and got admission for MBA in Canada. Foreign universities doesn't only look for your undergraduate CGPA rather it looks for other things like:
1. Your GRE score.
2. How good is your application?
3. Whether you have experience or not.
4. IELTS and TOFEL score and
5. Recommendations and much more things.
So, you can apply and get admission too.

Hello Lavanya,
While Germany becomes a little tough nut to crack and DAAD is the official site to look at. Canada seemingly is easier to get in. Universities like:
1. University of Toronto.
2. University of Alberta.
3. University of Ottawa and
4. University of Saskatchewan, etc. would have the course and would require a 4 years of Bachelor to apply with a TOEFL score and GRE (recommended).
You would have to apply a year in advance with statement of purpose and letter of reference submitted with the online applications.

You can apply for MS electrical engineering. Since, Masters in Canada is competitive, you can look for other post graduate programs alternatively such as wireless telecommunication, wireless networking, embedded systems, etc. They are offered by the community colleges and are very practical learning oriented.

That time has gone. Earlier, the time was good. MBA from abroad means safe future. Now, it will be suicidal to invest this much money just for MBA and still no job guarantee. Please don't do that.

I think you are confused with your career, so first of all decide carefully about your career as your future depends upon it. I think you are saying 92% in 12th boards.

You can get a specialised Master's degree program in computer science in Canada which are well recognised across the globe and have strong industry collaborations. However, they are very competitive.

It normally requires 6.5 IELTS with no band less than 6.0 in order to pursue Masters in engineering from Canada.
