Hi there, today, i thought of making this post as if this is the most commonly asked question by people who are trying to apply for education overseas.
In United states, Topper in the class get 4.0. so, as per that, for example if one gets 75% being the topper, then he gets 4.0 . In that case, 60% would be (60/75)*4 = 3.20 .
Summary:
Class Topper gets 4.0 and rest of the students GPA is based on that level. And vice versa for percentile score.
i hope this post helps! .
