All you need to do to get better is play. I've been playing for 6 months in standard osu! now, and I can Doubletime Hidden Hard songs, and easily fullcombo insanes, it depends on how much time you spend on the game, and how fast you learn. Play easy songs then move on to hard when you can easily play easy songs, then after that, move on to hard songs, etc.
