What does Percy decide to study for the Latin exam even thouth given up on his other subject?

You're likely thinking of Percy Jackson from the book "The Lightning Thief" by Rick Riordan. Percy struggles with Latin, but ultimately decides to study for it even though he's given up on his other subjects. However, he doesn't study for the Latin exam in the traditional sense.

Instead, he chooses to focus on memorizing the Latin words for "monster," "monster food," and "monster weapons" because he expects the exam to be about monsters, not Latin grammar.

This reflects Percy's unique perspective as a demigod, where his real-world knowledge of Greek mythology and monsters takes precedence over traditional academic learning.
