However, it's important to note that:
* Reading level: While the vocabulary and themes in "The Great Gatsby" are complex, the actual reading level is not overly difficult. It's considered appropriate for middle school readers (grades 6-8) with some guidance.
* Content suitability: The novel explores mature themes like love, loss, wealth, class, and the American Dream. These themes may be more appropriate for older audiences, but they can also be addressed and explored in a thoughtful way with middle school students.
* School curriculum: The grade level at which a book is assigned can vary depending on the school, the curriculum, and the teacher.
Ultimately, the decision of when to read "The Great Gatsby" should be made on a case-by-case basis, considering the individual student's maturity and reading ability.
