Australia

Dear Harry,
You need a minimum of 65% or equivalent in your class 12th and an IELTS score of 6.5 overall with no band less than 6 for the majority of the universities. However, there are a few which will accept overall 6 with no band less than 5.5.
All the best.

Dear Mandar,
Yes, it will be helpful if you do your MS in Australia in the same line. You need to do your IELTS and score overall 6.5 with no band less than 6 for majority of the universities and at the least should have 65% or equivalent in your BE.
Your work experience will give you an edge, when you apply for work later, also do not choose an MS with less than 2 years duration as this will make you ineligible for PR later on.
All the best.

Dear Ranju,
The minimum is overall 6 bands with no band less than 5.5.
All the best.

Dear Nahid,
I would suggest you do MS in the same line and choose a specialisation in which you are interested. While selecting the course and university, you can select the college which offer you an internship at the end of the course.
This will increase your chances of getting employed in the same firm, where you will do your internship as you already have 2 years of experience and if you perform well during the internship. It helps if your 2 year experience is with a known company and yes, IELTS and your academic scores are enough.
All the best.

If you want to get placed in top universities, you need to have work experience in related area or else you can consider any consultancy services to get additional information.

Hi Gauresh,
Please reframe your query, it seems to be incomplete. You may add details in the description column.

I would request you to retake the IELTS as your visa may get rejected at this score. You must try to score 6.5 and above.

You must go for Australia as it is difficult up there in New Zealand.

You can find scholarship information on the university website, so please check the website of the university you want to apply to. Universities have merit scholarships and applicants are considered by default when you apply. But those are on merit and for bright students.
