In my opinion, most developing and developed Asian countries do have harder education than Western countries. However, I have seen a lot of Indian students in this forum with 50% in high school and still getting admission into Indian universities.
With 50%, no Canadian university would ever accept you.
Nobody can get admission in renowned universities of India with 50 or 60 percent marks. On the top of that entrance test is separate for admission. Like LPU, PUNJABI UNIVERSITY, PUNJAB UNIVERSITY, DELHI UNIVERSITY.
Actually college accept these students which are affiliated to renowned Universities.
And the average cutoff for renowned government college in India is 70-75 percent.
And in India education system focus on theory more rather than practical.
That's why percentage of majority students remain between 55-65.
