Letter Grade Calculator

The letter grade system commonly used in Turkish universities expresses 100-point scores as letters: AA (90-100), BA (85-89), BB (80-84), CB (75-79), CC (70-74), DC (65-69), DD (60-64), FD (55-59), FF (0-54).

The 4.0 grading system is the numerical equivalent of letter grades. AA=4.0, BA=3.5, BB=3.0, CB=2.5, CC=2.0, DC=1.5, DD=1.0, FD=0.5, FF=0.0.

Generally, courses are passed with DD (1.0) and above letter grades. However, in some universities, DC may also be sufficient depending on the overall GPA. FF and FD grades are considered failing.
