When the beatmap ends you get a letter grade depending on how you did right? Can someone explain how the A, B, and C scale works out? I know how S and SS work, but I thought it was suppose to be 80% for a B and 90% for an A?I have had times when i finish a beatmap with a 85% yet it still counts as a C. Same applies for beatmaps that i finish with 92-93% and end up with a B. Naturally, the letter grade is less important than the score, but a C looks depressing to see even if the score is fairly high. Thanks in advance!
