## Scoring

### Judgement

Judgements are based on the timing when the note is tapped/held. Each judgement affects the score and combo when playing, and each judgement contributes a different amount of score.

Each note's EXCELLENT judge equals to the main score rating of a song that multiplied by 100.

The formula of calculating score is: [EXCELLENTs + (GREATs × 50%) + (SAVEs × 25%) + (BADs × 10%)]/(Total Notes) multiplies 1000000 score.
