Percentage scores are often used when grading tests and exams. Various tables exist for converting to school grades. Here is the standard conversion table used at most Czech schools.
| Percentage | Grade |
|---|---|
| 90-100% | 1 (Excellent (1)) |
| 75-89% | 2 (Very Good (2)) |
| 60-74% | 3 (Good (3)) |
| 50-59% | 4 (Sufficient (4)) |
| 0-49% | 5 (Insufficient (5)) |
Each school or teacher may use a slightly different conversion table. Always follow your school's or teacher's guidelines. Some schools may have stricter or more lenient criteria for individual grades.
