How do I prepare for my AP English language study in the next year?

I will select AP English language in the 11th grade. I know it is tough. What shall I do in this semester and summer to get prepare for it? Any online course recommended? Any vocabulary I need to remember?

May be get an online English tutor to guide you through. What do you think.

My DS prepared by using reading a lot in his free time, so this is one thing I would definitely recommend as it helps you obtain a strong foundation. For AP Language specifically, it would be best to familiarize yourself with the rhetorical devices and the contents of the exam (the essays). Advanced Placement youtube channel would be beneficial in this regard.

Thank you for your advice!
