First, weighted GPAs are used for weighted classes. These classes are the honor-type, higher-level classes (also assumed to be more difficult) having bigger worth than your regular class subjects (unweighted classes).
Take AP/IB classes and get good grades. I think GPA (unweighted) is looked at first and then the HPA (what we called the weighted GPA) is looked at. To know the rigor of your classes, schools look at your transcript. HS can use whatever weighted GPA system they want to.
