The title of the post is help with a controller... and it sounds like the OP is asking about completing it, not necessarily getting gold. (So all this get a wheel to gold it is rather away from the OP's question, begging your pardons!)
If you're looking to complete it with a ds3, the #1 advice I've seen a few times is to pump up the controller sensitivity!
Since I seem to do best with my sensitivity lower than most, not sure this would help me, but I haven't even tried it.
I watched my bf try it once or twice, and he put it aside for another day, though I don't think he was far off. We're both ds3, casual middle aged "sofa players", & we've only had the game less than 2 months.
So don't let anyone discourage you if you're having fun trying!
