What 233.3% Means as an A+ Grade
Excellent standing. A+ is the top grade on the US scale; it meets every Dean's List and merit scholarship threshold.
At most US colleges and high schools, the minimum passing score is 60%. A score of 233.3% clears that threshold, so 70 out of 30 is a passing grade. Always verify with your institution, as some programs require a C or higher (70%) for courses that count toward major requirements.
