I have 20 backlogs in engineering and have completed all of them in 2 attempts. Am I eligible of pursuing a Masters course in any country?

You should have completed your degree in 4 years and you should not have any live backlogs.

You can, if you have extra talent and innovative ideas.

First of all, it will create problem for you if you have not completed your engineering in 4 years because , extension of degree duration is hard to justify Secondly you can opt for unconventional study destinations like Poland, Ukraine and other eastern european countries etc
