There is a myriad of grading systems in Brazil. The most popular are:

Percentage point grading system: ranges from 0% to 100%
Scale grading system: ranges from 0 to 10 (0 represents the lowest and 10 represents that highest)
Stage grading system: usually uses letters ranging from A (best) to E (worst)
Below is a summary of the grading systems:

"A": 90%-100% (Excellent)
"B": 80%-89% (Very good)
"C": 70%-79% (Good)
