Give brief factual context if it materially changes how the GPA should be interpreted.

Some recruiters know school grading patterns, but you should not assume every reviewer will.

Official class rank, honors thresholds, or a published grading note are stronger than simply saying the school is difficult.

Report the GPA accurately and add official context where the application gives you a place to do so.

Official rank or honors cutoff is stronger than saying grade deflation.
