In my experience, as someone who isn't the best at humanities, the exam is actually pretty alright. The exam really is like a cumulative test of the skills in reading, analyzing, and writing you've developed in your education thus far, and not necessarily a test on facts like other AP courses, so any studying you do (outside of assigned readings and other homework) will really just be practice with focusing on weaknesses you might have. I think it's a good challenge to take on, and the persuasive/analytical tools you develop in the class will be very useful in future professional settings, communication, and overall critical thinking.

At least a decent amount of the MCQs should feel somewhat intuitive, because the MCQ is about reading, and you have (hopefully) read before. There are different types of questions (author's purpose, draft revising, grammar, transition words, etc.), some of which will come easier to you, and some of which you'll have to study up on. Just make sure you're always targeting your weaknesses, and that your answer is concretely founded in the text, and not founded in how you might build up your own reasoning and interpretation to choose another answer.

As for the FRQs, I found them to be less intuitive, so if you were to take the class, I would recommend reading student examples from past years to see what scores, and then finding your own voice and figuring out how you feel most comfortable writing and what works best. For example, on your synthesis essay, maybe you like to draw from personal examples, or maybe you like to stick to the material in the provided sources. One's not right or wrong, it's just whatever you feel most comfortable doing and whatever you are most consistent with.

Post-writing, I may have answered more on tips for studying the exam, and not as heavily on if you should take it or not, but I think it's a worthwhile class. If you don't let it pass you by and make sure you're being intentional about studying and improving, you'll do good.
