IELTS

Hi Samriti,
Your spouse can apply for the visa while you are applying for the student visa. Now, the question is your profile. Any good university will require work experience, GMAT score and higher percentile. Also, you already have done M.Com so universities will question you why an MBA now? First check with some universities and then apply. Also, keep alternate options like Australia, France, Netherlands, etc.

You should take IELTS.

Hi Dinakar Kuchi,
A majority of the universities require 75%. You will most likely find very few options in Canada. Check University of Alberta, McMaster University, University of Windsor, Dalhousie University, etc.

Hi Prerana, yes IELTS or TOEFL is generally required.

Hi Alvin, this mainly depend on the visa officer evaluating your profile but it's better not to take chance without IELTS in European countries. Also, it will hamper your job prospects later. Check with the school first if they can accept you without IELTS and you should prepare a strong application accordingly.

Just enroll in some good speaking classes. Mainly focus is on three things writing, reading and speaking. You need to require minimum 6 bands in each of them. When you feel confident that you can speak English with ease. You can go for the test. Exam fee is about rupees 12000 and exam takes place every month.
Good luck.

Hi Syed, you must register on their official website. Once you register, you can schedule your test and test center, pay the fee and take the exam accordingly. Just check the websites for details because it's not possible to mention every single rule here. Here are the links:

Scholarships are given by the universities on the basis of merit to international students. You must be academically very sound and have a good profile overall to be deserving. Getting a job will also depend on your qualification, skills, academic performance, etc.

Dear Vaibhav,
Yes, you can pursue a Masters with ELICOS certificate if you do not want to retake IELTS after some good coaching, a lot of people opt for retaking this as the cost of ELICOS is much higher. In fact, I am processing a student for Masters with ELICOS in accounting.
All the best.

Hi,
Unfortunately, not. You must take the GMAT or the GRE and possess at least 3-5 years of work experience for an MBA in New Zealand. IELTS requirement is usually 6.5 and above.
