IELTS

Hello Brajesh Rathore,
Below 2.5 lakhs is a very low budget, Canada seems difficult. Normally courses abroad will range from 6 to 7 lakhs onwards.

Hi Sandhya,
For better guidance, you must mention your education background, desired program of study and what type of job opportunities and in which field.

GRE is not mandatory. IELTS must be taken by all international applicants, even if you have German language knowledge.

The universities does not require any other tests. GMAT or GRE are usually for the top ones, so if you want to get into an average college, you may have a chance. You can also check popular colleges under SPP.
Some of the decent options could be:
1. Vancouver Island University.
2. Thomson River University.

Hi,
A good band score (say 7) will get you into countries like UK, Australia and Canada. There are tons of universities in Europe that accept IELTS for selection. However, you might want to check the university website if your preferred course is available in English. Take language proficiency tests if necessary (in the case of European universities). If you are keen on getting into American universities, you need to appear for GRE. But, some universities accept applicants without GRE. That being said, it totally depends on the country you've chosen for graduate studies.
All the best!

Canada is a better country but try to get 7 bands so as to become safe.

According to me, there is no criteria except you must be above 18 years of age. Kindly, check ielts.prg website, create an account, pay the fee and schedule your test. There are certain rules for cancelation and rescheduling.

Yes, you can. They accept students even without IELTS.

Yes, the admissions will depend on your improvement, GRE scores and overall profile.
