IELTS

Hello, do you mean admission? You haven't specified your grades firstly. Please be more specific with your question.

Hello,
IELTS is an English language proficiency test. You will be required to take it, if you desire to study or work abroad. Every foreign university accepts IELTS scores.

TOEFL or IELTS exam will help you in getting the student visa, so you must take either of them. Some universities may accept the certificate but it is better to take a standardized test.

Hi,
You need GMAT score in many of the universities at Canada.
You can check the below mentioned link and apply as per suitability:

GRE boosts your application. You can check the university requirements.

USA, UK and Australia are the kings of education.

You should appear for JEE Mains exam. UPTU State level exam also has a quota for other states. If you belong to UP, then it's good because UPTU examination is very easy as compared to Mains.
If you are interested in private engineering colleges, then try to qualify the following exams:
1. VITEE
2. FITJEE
3. BITSAT

It is hard for you as you have 11 backlogs and your IELTS score is less. So, chances of visa rejection are more.

Anything below 55% makes it very difficult. You can still try for Australia, and European countries like Belgium, Italy, Poland, etc.

Hi Navi,
5.5 band is generally not accepted. You need to score 6 band or more. Please write to the colleges and also check if you meet the academic requirements which are very important.
