IELTS

Dear Shaunak, no accredited university will grant you admission without a GMAT and work experience. Therefore you will be required to take the GMAT.

Australia is best.

Why not? You surely can.

Dear Divya,
ILETS is a English proficiency test, taken for admission abroad, all the universities requires ILETS/TOEFL score for candidates from a country where English is not first language or native language. Proficiency is rated on scale of 10 now requirement varies from university to university.
All the very best.

Dear Mayur, have you checked with the requirements of the universities you desire to apply to? normally a score of 5 is not acceptable but might be considered under certain circumstances depending on your profile overall. An IELTS of 6.5 ( with no section less than 6 ) is required mostly.

Hi,
For a Diploma course it can be 60% and degree course, it will be higher. If your percentage is 80% and above, you will have better chances of good universities. For IELTS 6.5 is good enough. Start shortlisting universities as per the course and check their specific requirements as well.

You need to work very hard if you want to study abroad.

Hello,
The IELTS or TOEFL is one of the requirements for candidates to live, work or study in an English-speaking country. Remember, it is not necessarily a visa requirement. There is no guarantee that you will be offered a job only on the basis of IELTS or TOEFL, of course probability will be higher. You need to have the required academic qualification and additional requirements for a job. So, unless you are qualified IELTS or TOEFL won't have benefits regarding your career.

Dear Ayaz, almost every university accepts IELTS, though in US TOEFL is given higher preference.It would be difficult to check the requirement you are looking for, the best way would be for you to first decide which country you want to go to and check the top university websites for admission requirements. Refer QS world ranking, Times higher education ranking to learn about the universities.

Hi,
You need to learn and improve your vocabulary to speak better English. The more you practice, better it would be. Speak as much as possible and if you have someone to correct you, do not take offence. You may also go for some professional coaching as you will get a group of similar interest.
All the best and happy speaking.
