IELTS

Hi Dhruv,
IELTS alone is not used for admission. You must also have the sufficient academic scores. Your IELTS score is fine except the writing score. But you can check with universities for bridge courses in English. You have to check the university websites for specific admission requirements.

Hello, typically you are required to gain 2 to 3 years of work experience on completion of your Bachelor's degree and also take the GMAT or GRE. You may take either one of TOEFL or IELTS. For the average score requirements you should visit the university websites. MBA programs in US are regarded to be among the best and most selective in the world. They look for all-rounders and candidates who can contribute to the class on the whole.

Hello,
Canadian MS degrees are highly competitive. They are either course work based or research based. It is slightly easier to get into a course work MS program compared to a research based one. High academic grades, demonstration of research work such as publications etc are required. If you are opting for a research based program you must be accepted by the research supervisor of the particular university/department. GRE may be required but not mandatory mostly. I will advice you to start visiting university websites for the entry requirements and deadlines. Apply early. Feel free to revert for any clarification.

IELTS is valid only for two years. Take IELTS again. Take GRE with good score, and then apply.

No.
IELTS is compulsory.

You can do in certain countries. France, Dubai and a few other countries will accept without IELTS. UK, Ireland, Canada and New Zealand will surely need IELTS.

Hello,
Yes, if it's an undergraduate degree. Also, you must check the academic requirements and not only the IELTS score. Every college has its own requirements, suggested you check the websites. Feel free to write back for any clarification.
