hey and keep playing (ik people say this alot) find a difficulty your comfortable with once you can at least get A or S start moving up difficulties thats the best advice i can give and done feel down about your skills rn as you will look back in a few months or even a few weeks and see how much you improved id also recommend every now and then if you get a B watch your replay see where you went wrong and what you could do to improve (dont do this for all plays just plays where you dont understand how you missed or got less accurate hit) either way just have fun the rest will come later
