User blog comment:TheSonofNeptune/Is Percy Jackson going to have to repeat a grade in Highschool?/@comment-6064271-20130123230800/@comment-5774152-20130328005241

Step by step shall we?

The Lightnig Thief: Percy just ended 6th grade

The Sea of Monsters: Percy ended 7th grade because it is the summer after The Lightning Thief.

The Titan's Curse: Percy is in 8th grade because it is the following winter after the The Sea of Monsters.

The Battle of the Labyrinth: It is the following summer after he was done with 8th grade, therefore, he is about to go into 9th grade.

The Last Olympian: It is the next summer after The Battle of the Labyrinth, so now he is going into 10th grade. Couple months later he goes missing, so Freeballer is right. He was in 10th grade.

@Freeballer34, please use periods and capital letters at the beginning of sentances. It's really hard to understand you when you don't.
