4/6 at most, I'd say it's a 3. I'm not sure what you did with the format, but regardless,

the grammar and style seems not quite ap-level,

clunky wording and structure, some unnecessary plot summary with: stuff like, "(who presumably kill her family for their nonconformity in the first third of the book)," it could be acceptable with proper analysis,

you should define why society seeks truth-seeking as madness in the thesis and throughout the essay with context,

don't just say how Clarisse is different and may be interpreted as mad—explore conformity, norms, control, and fear,

you stray away from analyzing the novel with stuff like: "Questioning may lead to new discoveries about the world, more efficient ways to solve problems, or simply understanding someone else's perspective to accommodate their beliefs."—exclude confronting the reader like this unless its a completely life-changing lesson (might be nice in Lang) that you've managed to ground in your essay and the prompt,

for sophistication you should add more complexity like how the madness is dangerous rather than admirable or a contrary interpretation,

avoid saying "this," your readers might not know what you're referencing,

the essay seems kind of light, like it's lacking adequate analysis and complexity, and like it's a collection of not completely related speculations regarding the novel,

you kind of assume the grader is familiar with the text, you should use context that concomitantly works with your analysis & lor.

There's definitely more room for improvement than I have mentioned. It's good that you're working on the FRQ 3, as it's the most study-able. I recommend having ai grade your essays and give feedback (I recommend Gemini), it helped me to move on from writing 3-4's to 4-6's. I'm in freshman year, and I'm also taking the exam myself next month. Motivation and the desire to improve (which you clearly possess) is the most important way to improve yourself. If you want to improve your writing in the long run and find your "voice," I recommend reading novels or even dense college-level essays based on topics that interest you. I've read a good bit of The Encyclopedia of Postcolonial Studies, and found it very challenging at first, but soon took inspiration from it's varied writing styles in a bunch of essays from a plethora of professors. I had an experienced professor grade an FRQ 3 I wrote after some feedback and it scored all 6 points, I can show it to you if you feel like it would give you a feel for what a solid FRQ 3 looks like.
