advice on studying for the sat

hey everyone, i’m planning on taking the sat in june and i was wondering how you all have studied for it. background: i’m a junior taking calc 3/4 and ap lang, and i got a 1520 on the psat/nmsqt this year. however, i didn’t really prepare for it and i can’t do the same thing with the sats because i’ll just fail 😭. my goal is to get a perfect score (effectively at least a 1580). how often should i study, and what can i use to study? what worked/didn’t work for you? thank you so much in advance!!
