    "context": "Plus/minus grading changes the result materially: most schools use A− = 3.7, B+ = 3.3, B− = 2.7, so the difference between B+ and A− across a semester is about 0.2 GPA points. Weighted high-school GPA adds 0.5–1.0 for honors/AP courses, which is how valedictorians exceed 4.0. Check whether your school caps weighted GPA or reports both weighted and unweighted.",
