Hi @MathMomVT!! Your rfriend here.
My daughter went to one school 9-10 grades with 0-100 grading. Then she went to another and did an IB Diploma for 11-12 grades which is 0-7. Never knew what her 4.0 scale GPA was…colleges figure it out. The only time there was an issue was for our State Flagship which awards scholarships based on GPAs , but a quick email sorted that out. So send your transcript and the college will figure it out.
