IELTS

Hi Jay,
This is a difficult question to answer. There are thousands of universities abroad and also you must be more specific about the country choice as to the university which will give you the admission will entirely depend on your overall application profile and the university's selection process. If you are planning for US, getting into a top university with 301 score in GRE will be tough. It is important that you first decide the country, start visiting university's websites across popular countries and check the requirements and shortlist accordingly.

To get 6.5 bands in IELTS is not difficult at all. You just have to be familiar with the exam pattern and a practice of 1 to 2 months is enough to crack IELTS paper.
Moreover, keep in mind that IELTS is widely accepted in all European countries, while TOEFL is favoured by USA and UK.

No, you need to take GRE and for automotive systems, I would suggest to try German Universities. You can check their websites.

You need to take GRE or GMAT, depending on what course you want to pursue. For MBA, which needs minimum 2 years of experience, you can go for GMAT and try to score above 680.
For other courses, you can take GRE and try to score above 315. You can check on the website of the universities offering courses of your interest.
UOT is the best in Canada.

Hi Lovedeep,
Can you mention your academic background, grades and what you want to study?

Hi Nikhil,
I would suggest you to start your preparation from the 2nd year, but you should write it in either 3rd or 4th year because GATE and other exams cover the course of mainly 2nd and 3rd year.
If you are applying for fall, you should take latest by July or even before that, so that after writing it once you can think about a second chance, if not happy with your score, otherwise you start building up your SOP and search for the right place to go.
All the best.

It depends on the level of university and the course, which you choose. There is no age limit to pursue a course, but it is definitely a criteria for embassy while deciding to give you visa or not. For Master's course, the maximum age as per my experience is 35 and for Bachelor's, it's 24. Beyond this, you should apply for Ph.D. IELTS is not a country requirement as it's not an English speaking country, but certain universities will ask for 5.5 to 6.5 band for courses taught in English.

Which course and university have you applied to?

You have to score at least 6.5 overall with not less than 6 in any module, but try to get more to make your profile good.
