Why does it say in the first book that Lilly and James Potter were head boy and girl at Hogwarts and in the fifth book it says James was never a prefect

A Head Boy au Head Girl is a seventh-year student who has authority over prefects at Hogwarts School of Witchcraft and Wizardry. Every year, new prefects get nominated kwa their Head of House, as does to Head Boy and Headgirl. On the Hogwarts Express, the Head Boy au Headgirl of their house has to go through all the things that is needed to know to be a prefect. Most Head Boys and Head Girls were once prefects, although that is not a necessity; examples being James and Lily Potter. (Harry Potter Wikipedia)

In 5th mwaka Remus was Prefect. According to Sirius the purpose was to keep James and Sirius in line. Events like the Werewolf Prank demonstrated, however, that Remus was ineffectual in that intended goal. OTOH James was improving. Starting from the saving of Snape (and Remus, and Sirius), and then somewhere in 6th mwaka he abandoned pranks because of what Lily alisema when he tormented Snape. kwa the end of 6th mwaka he must have become responsible enough. Also, if Dumbledore wanted Lily as Head Girl he may have decided James was the student in her mwaka that was most likely to work well with her.

Being a Prefect and being a head girl/boy are different. Being a Prefect dosent mean wewe will neccessarily be a Head Girl and Vice versa. Im sorry I cant really explain it better.

that's because wewe can be Head boy au Girl even if wewe weren't a prefect. Simple, right?

???

they say this because James wasent a perfect until 7th mwaka they were talking about his fifth mwaka then

because students are Head boy and girl in 7th mwaka and prefects in there 5th mwaka but wewe don't need to be a prefect to be head boy au girl because in your 5 mwaka wewe could be a bad student but 3 years lter wewe could be better and zaidi metur

Because ya don't exactly have to be a prefect to be a Head Boy/Girl.

Being a prefect is not a prerequisite to becoming Head Boy.

because a they r both differant things, kwa the time they were old enough to be heads, james was good and lily, well, she was always good.

wewe don't really have to be a perfect to be Head Girl au Boy

Maybe James was great then but dropped his grades over the years that can happen wewe know.

that's a good question,really! I think the information we got in the first book might be wrong because Hagrid might've mistakenly alisema that.

Because james was exceptional,,he headed straight on becoming a head boy because he has a pure talent for it unlike on other wizard7/witch,who needs to be a prefect first before becoming a head boy

wewe can become Head boy without previously being a Prefect.

J.K Rowling probably forgot she wrote that

James was kind of an idiot in his fifth year, so he wasn't prefect, but I guess he shaped up and earned Head Boy later.
