Mod score calculator:

• You can either write your username and auto-calculate your score, or manually write your mods count in the boxes above
• This calculator is only for your own reference. You do not need to input your mod count to apply for BN
• A "mod" is counted for each beatmapset through which you have received at least one Kudosu ("thumbs up" on discussion page)
• Scores 0 or higher are passing
• Selecting a different game mode above may impact your mod score (osu! has stricter requirements than taiko/catch/mania)
