Step by step: 33 divided by 42 equals 0.7857 as a decimal. Multiply that by 100 and you get 78.6%. On the standard US plus/minus grading scale, 78.6% is a C+ grade, equal to 2.3 GPA on the 4.0 scale.
What 78.6% Means as a C+ Grade
Average. A 2.3 GPA clears the 2.0 academic probation threshold but falls below the 2.5 GPA floor for many financial aid and honors-program requirements.
At most US colleges and high schools, the minimum passing score is 60%. A score of 78.6% clears that threshold, so 33 out of 42 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.
