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

First of all Percy is not in 11th he is in 10th in TLT he was in 6th in SoM he finished 7th, in TC (wich happened the same year as SoM) he was in 8th, in TC(bout 6 months after SoM) Percy is bout to enter high school where he see rachel elizabeth, in The last olympian he finished 9th grade n in the end he says for the first time he is gonna be in the same school for 2 straight years. Heroes of olympus happens within the year after the last olympian. Regarding ur question like alot of ppl i really believe the mist is gonna cover it in a way wher percy is missing n maybe when he comes back he will take a couple of extra classes to catch up or maybe rearrange the mist so that ppl think he never missed class. Or maybe he quits school n decides to go year round in at camp n learn from chiron as he teaches the year rounders(at least what i heard). hope that helps u in ur doubt
