IELTS

It would be better if you go for MS in Canada rather than PGD.

If you want to go to Canada then you have to increase your IELTS from your current score to 7 overall. It is the same for other countries also.
If you want to go for work then you are required to score 6.5 overall.

Normally, Universities requires 6.5 band and minimum 6 in each module. If you are looking for admission for 6 band and each module not less than 5.5, then you can look into colleges. You can see Sheridan College.

Yes, you can easily go to Canada for job, you can find relevant exam details on shiksha.com website and apply for same.

Hi,
MBA eligibility in the universities you mentioned is a good Bachelor's degree, 2-3 years of solid work experience and a very good GMAT score plus strong LOR, essays etc. NUS and NTU are extremely competitive, 570 GMAT seems quite low for admission in these universities. Average recommended GMAT is 680+. Besides these universities you will find a few foreign university campuses and private colleges offering MBAs from foreign universities which you can look up.

Hi Gurjeet, the question is very incomplete, what do you want to study? Or, check the website of the college and check the eligibility criteria. You will see the admission requirements, prepare accordingly.

Scoring 7 is safe in trying for higher studies abroad.

University website itself says list of requirements, but in case of language subjects, you need better score for preference.

Hello Gangareddy,
It is very nice to hear from you that you are interested in doing your Masters in Canada. It is a good choice. English as medium of instruction, great opportunities for employment as soon as you finish education, reasonable cost of living and quite rational fees. I am attaching a link that will give you all the required information about different colleges offering this branch. https://studyabroad.shiksha.com/canada/ms-in-computer-science-engineering-colleges-ds
Best wishes to you.
