Percy would likely be drawn to the Forbidden Forest. His adventurous spirit would lead him there. He might encounter magical creatures that are completely new to him. He could try to communicate with them using his own experiences with mythical beasts from his world. And when it comes to classes, he'd have a hard time with some like Potions as it has no equivalent in his demigod training, but he'd probably excel in Defense Against the Dark Arts as he's used to fighting all kinds of dangerous foes.
He might initially be met with suspicion. The Hogwarts faculty are protective of their school and students. However, Percy could win them over with his courage. For example, if there was a dangerous situation, he would jump in to help, just like he did in his demigod adventures. Professors like McGonagall might be impressed by his loyalty and sense of justice.
Percy would adapt to Hogwarts in a unique way. Since he has experience dealing with strange creatures and magic in his own world, he'd likely approach the Hogwarts magic with an open mind.

He'd also bond with some of the students over shared values like loyalty and bravery.
In a fanfic where Percy goes to Hogwarts alone, he could form some interesting friendships. He might befriend Neville, who is also a bit of an underdog.

In this fanfiction scenario, Percy's adaptation to Hogwarts would be a complex process. He'd first have to deal with the cultural shock of a new magical world. The Hogwarts houses would be different from the cabins at Camp Half - Blood. He'd need to figure out which house he belongs in. His skills with a sword might not be as useful as in his own world, but he could learn to use magic to enhance his combat abilities. Also, he'd have to make new friends and enemies, and learn how to navigate the social politics of Hogwarts while still holding on to his own identity as a demigod.
In this scenario, Percy would likely use his unique demigod abilities. His skill with water could be used in various ways, like putting out fires from spells or using water currents to disarm enemies.

He probably feels a bit scared. Hogwarts is a big and strange place, and without his family, it can be intimidating.
Some students might be in awe of him. His demigod status and the stories he could tell about fighting monsters would be really cool to them.

But then there would be those who would be friendly and curious, like the Weasley twins. They would probably want to team up with him to pull some epic pranks using his unique skills.
