IELTS

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.

6 band in IELTS is not enough to get a student visa. I can suggest universities which accept 6 band and you can get admission successfully, but your visa will get rejected which means you will lose the admission fee for the first semester as you can't fly to Canada. So reappear for IELTS exam and aim to score at least 6.5 band or above.

Hi
The best way is to check a mock test available online and attempt it as different people have different abilities. Also, it depends on your instructional language to know your proficiency levels.

You need to appear only in GRE and IELTS for the same.

You need 6.5 bands in IELTS for a good college.

Yes, you can apply for January, 2017.

No, you cannot get admission. You should reappear for the IELTS test.
