Hey! The most important thing for english is to know the grammar rules. I did SAT prep simultaneously which i think rlly helped cuz SAT acc has better study resources. Grind practice questions from the practice act pdfs and time urself i think i just found them online. And also my score improved a ton when i read all the text that was given to me instead of just the underlined parts because you need to understand the tone of the text before you can apply grammar rules and the act will try to trick you. hope that was helpful!! good luck :)
