But not all HS’s weight grades. There is a reason colleges do their own gpa based on grades, not extra points given by a HS. You live in your world but life is different elsewhere. A special ed kid can make the honor role (I once asked a teacher about this and class ranks, he assured me that those students would never replace those in the top ranks- 2000 or so HS kids).
I find it funny bordering on ridiculous to see the Tampa, FL area gpa’s for the top two students in various HS’s each spring. All on a 4.0 scale but some get below a 5.0 and others nearly an 8.0- not all schools offer the same numbers of AP/Honors classes (often based on demographics- some parts of the area are rich, others poor). It would be interesting to see the unweighted gpa’s.
Also, some schools use + and - to add/subtract fractions of a point. I learned from the mother of gifted twins that her son would do the work to barely get an A while his sister would do A++ work to get the same A grade.
Getting top grades by doing the busy work in addition to knowing the material is a reflection of life after school. You will be paid not for what you know but what you produce/added value. All of the ability, potential or knowledge in the world is meaningless to society without benefitting society in some way.
