The old 7K Dan course forum was getting really old, so I decided to just make a new forum post.
With the completion of all the regular dan courses, I thought the map descriptions became a bit too cluttered so I decided to add information about the 7K Dan courses in this post.

You may have noticed that there's a new extra dan in town! Featuring Stellium Dan, aka "The Epsilon Dan of 7K". It is meant to be almost impossible to pass, so good luck to anyone who even dares to tackle this behemoth.

So without further ado...

How does this dan course work?

A "dan (段)" can be thought of as your skill level. These courses are designed to show which "skill level" you fall into. In order to pass a dan course, you must achieve an accuracy of 96% or above (for regular dans) and 95% or above (for LN dans). You are discouraged from pausing during the course, as stamina is also a part of the skill that these dan courses test.

The Dan courses are separated into two types, Regular and LN. Regular dan tests your basic abilities with the exception of Long Notes, which is what the LN dan tests.

The Regular Dan courses feature four maps, each testing a range of different skillsets:
- The 1st map is a jack style map, which tests your abilities on jackhammer patterns such as minijacks, long jacks, and chordjacks.
- The 2nd map is a tech style map, which tests your abilities on a variety of technical patterns and looks at your versatility overall.
- The 3rd map is a speed style map, which tests your abilities on fast streams / burst like patterns and looks at your finger speed.
- The 4th map is a consistency / endurance style map, which tests your abilities on extended chordstreams and tests your stamina.

The LN (Long Note) Dan courses also feature four maps, each testing a range of different skillsets:
- The 1st map is a general style map, which tests your abilities on different kinds of common long note patterns.
- The 2nd map is a tech style map, which tests your abilities on a variety of technical LN patterns and looks at your versatility overall.
- The 3rd map is an inverse style map, which tests your abilities on long note inversions and tests your finger independence to the max.
- The 4th map is a release style map, which tests your abilities on LN releases and tricky patterns that test your reading ability and finger coordination.

Dan course map listing

All the beatmaps that were used to compile these dan courses are maps from various mappers. All credits go to the respective mappers. Thanks to everyone who helped me with finding suitable maps for the dan courses. Special thanks goes to Evening for the original bgs, and additional thanks to tailsdk for the new Dan backgrounds!

wew Jinjin ET and nice one.

Sorry for the off-topic request, but could you reupload the outdated 7k courses? The dropbox links are down.
