Yes, it equals the length of the course.

Although, you should go according to your area of interest but if you are asking for the job prospect then CS has an upper hand as compared to mechanical and electrical. You can easily earn 30$ per hour after your degree completion.

Both the countries are great in terms of jobs in civil engineering, you can choose either of them. You just need to explore your skills, you can get jobs anywhere then.

Many institutes say that they will take students without IELTS, but it's not true, because if you get admission in any institute abroad (like Canada), you will still not be eligible, because in Visa interview you need to show the proof of your English language test's result, and they need 6.5 band in IELTS, so beware of those fake promises, study hard, score well and then go.
All the best.

Hello Ankith,
If you want to study embedded systems particularly, I'll suggest you to look into Europe. Few suggestions are:
KTH Royal Institute of Technology, Sweden
TU Eindhoven, Netherlands
TU Berlin, Germany
All three have really good programs in this course.

You need to score over 70%, but they need overall 80% for UG and over 75% marks for PG, so clarify first either you want to do BS or MS.

Unfortunately no, you are from India, so you have to prove your English language proficiency and for that IELTS is must. You can try Russia or Poland, they will accept you but they are not so good for study and jobs.

If your degree is accredited by UGC/AICTE, then your MCA degree is valid.

1. University of Toronto
2. University of British Columbia
3. University of Alberta
4. University of Mcgill
5. University of Windsor
6. University of Laval
7. University of New Foundland, etc.
If your UG score is above 75%, then you will get the admission easily.

Seneca is among the top 5 colleges of Canada. Yes, you will get a student work permit of 20 hours per week and you will get 20 CAD per hour for the work. Frankly speaking to meet the expenses student work for more time by telling their colleague not to tell anyone about how long they are working but one will get 14-15 CAD for that.
