Not to mention the fact that you could have three different high schools and one does GPA on a 4.0 scale, another on a 4.5 scale, then another on a 5.0 scale. My kid’s school actually took GPA points away if you were in the easiest of the classes (CP) so an A was not actually a 4.0 but more like a 3.8. I heard most colleges take the HS transcript and apply their own scale.
I’m hoping that his above average SATs, ECs and the fact that he was at a tough HS in honors class will be enough for James Madison, Michigan State or South Carolina to accept him.
