You will. Give yourself some time. Think back how you got as far as you are. How did you get here? By practice. It really comes down to mostly hours as long as you practice in a sensible way. Not rushing or going too easy.>>13632702
As said, clears. You can however start paying more attention to pgreats and trying to develop the habit of trying to get them. As charts get harder and more dense you won't of course be able to do that, but if you want try to still keep it in mind while playing and if there's say slower part go for pgreats. In general keep playing and eventually you'll get the feel for it. If it doesn't bother you much think about it like this: consistently being able to clear 12s is the beginning of the actual game where scoring becomes the main factor.
