It is reasonable to get admission to most institutions across various countries such as Canada, USA, Australia, UK, Ireland, etc.

* 5 - 10 backlogs are also accepted by many universities.

But make sure you have a good GRE/ GMAT score as well as an IELTS score of 6.0 or above.

* 10 - 15 backlogs 

In exceptional cases, it is seen in UK universities where students with 15 backlogs are offered admission on the basis of their performance in IELTS/TOEFL.
