I been playing these game for 2 months too,play more and don't retry the same beatmaps all over and over again
and play harder song but still playable for you if you want to improve fast at reading
or just try fc ing some maps but dont retry it over and over again.
what a mean is you play a song,can't fc try other beatmap,can't fc try other until your consitency is good and you will get used to it
oh yeah, and download a ton of beatmaps too,cause every beatmap have different shape and pattern and it help building you muscle memory
that method is kinda work for me but don't know with other
and don't forget to play for fun, the more you unconscious the faster you improve
