Play maps you actually get high acc in to get the basics dowm, then increase speed and difficulty.
If its just single patterns or certain things you get low acc on, do those things at a lower bpm first to get comfortable with the pattern and then speed up.
Focus on actually trying to do and click on patterns properly, not just comboing through it. If youre not completely sure what you have to in order to do the pattern correctly, you could check a replay or in the editor and listen to the hitsounds, and then trying to match your tapping to what you heard.
