Help with a study plan for this summer?

Hi! I am sure this will be helpful for a lot of rising seniors. I have taken the SAT 3 times and have a super score of 2160 (690 math, 730 reading, 740 writing). I am very frustrated, and looking to boost my score to above 2220. I have a math tutor who is really great, so I don’t need help with math. But in terms of the reading and writing section, I want to try to get near 800. What tips do you have for making a study plan for someone who already understands the test, but wants to get a nearly perfect score in the english sections? Thank you SO much!!
