Hi Manish,
You must ideally choose a course as per your interest and career inclination. What seems best for another applicant may not be best for you so the choice of courses is quite profile centric. Networking & Information Technology and Engineering Management are two of the many PG Diplomas you can pursue and these are some of the most demanding. Hope this helps.

ielts is enough but some top university may ask for gre score

Hi Ayush,
It varies from university to university. Top universities require higher grades around 75%. Colleges will accept 60% and above.
Thanks

You must research yourself Meet. Most universities will offer Ms programs and there is hardly a PGD in mechanical engineering. You will find technician courses though but it won't help much.

Hi Vikas,
You must initially decide what to study. Research on colleges in Quebec and availability of programs in the colleges. You must take TOEFL or IELTS. SAT is not mandatory but there may be department specific exams. Check other requirements, fees etc and shortlist the colleges you want to apply to. Be careful with the deadlines and submit the applications by tge deadlines. Hope this helps.

Hi Giriraj, either one is good. Depends on how you utilize your education to the fullest. Make your future plans clear and decide what to study. Best of luck.

In which branch did you complete your BE? It is difficult to get admission for MS. If you get it, you don't have to give a second thought about PG.
