I switched high schools halfway through my junior year and because my old high school was more rigorous and my new high school calculates GPA differently and doesn’t have a weighted GPA, my current GPA is much lower than it was before I switched (currently a 3.85). Should I somehow explain this in the additional information section of my Common App or should I leave it be? Thanks in advance!
