I need help with rush (Double included)

[Philadelphia_Joker]

Ok so im new and i want to be good someday :)
Okay so I'm able to make rushes like life goes on and alpha helix but when they put some doubles in the rush like left and right in the same time i'm ****ed up . I know i must pratice but i want to know if there is a particular song i should pratice?

Just practice. Try something easy and once you think you can do good try somthing harder and don't go quickly back to that easy song you just did. Stay on the hard song.

Rushes? Uhh, if you mean streams, then get Stepmania and practice on it then come back to FFR.
