well , i have been searching and found this website :

and there i found some of the mistakes that Rowling made while writing HP seires ....
Even witches make mistakes now and again, and JKR has made more than a few in writing the Harry Potter books!
Here is a short list!
In Harry Potter and the Philosopher's Stone, we read that the Elixir of life makes the one who drinks it immortal. Later on we hear Dumblodore saying that Nicolas Flammel has just enough of it to fix some affairs and then he and his wife will die. Which of course is impossible since they must have been made immortal!
"...come home every vacation with her pockets full of frog spawn, turning teacups into rats...,"
This is what Harry's aunt Petunia says about his mother, Lilly Potter. Which of course can't be true cos it was illegal for Hogwarts pupils to perform magic outside the school!
Hagrid and Harry leave the hut on the rock where the Dursleys had taken him on a little boat- the one they had used to get there. This of course meant that the Dursleys were left behind with no boat and no means of escaping!
In Hogwarts letter it says that Harry can bring a cat, an owl or a toad. The rat Ron brings is nowhere to be found on the list!
Ron is the knight in the game of magical chess played in the end of book1. Then it is said that he will have to move forward, so that the queen takes him, which is of course impossible as the knight never moces forward indeed!
In the first Harry Potter movie, all those letters that came for him. Well if the Durslys and Harry went on a small island of rock with no way of getting off how could they get rid of all those letters so quickly without any one in their neighbor hood noticing.
In Harry Potter and the Philosopher's Stone, we read that James was a HeadBoy but in the 5th book Sirius said that James wasn't even a Prefect!
In the 1st book Snape takes away harry's "Quidditch through the Ages" saying libary boooks are not alowed outside the libary but hermoine gave it to him to read
In the fifth book when Malfoy docks points from Harry and his friends, Ernie goes its only prefects who can dock points Malfoy. Yet in the second harry potter book, when Ron and Harry and Hermione were found in Myrtels bathroom, Percy who was a prefect does take points from Grryfindor
In the 2nd book Ron says that Fred had turned his bed into a spider. This is however impossible since no magic is allowed outside the walls of Hogwarts for students!
In book one, Harry shakes hands with Quirrell in his first time in the Leaky cauldron, but isn't Quirrell suposed tu burn when Harry Touches him?(
in book 3 when ron get pulled in the room with sirius black, his leg was injured so he sat on the bed, but when Lumpin came in it said Lumpin looked at ron who was on the floor
in the 4th book in the chapter were they turn so called Moody into crouch with the potion. When he is turned into Barty Crouch JR. and he starts confessing it says:moody said. But he is Crouch
in the third book, pg it says
"...the only person Harry had heard the name (apart from himself) was professor dumbledore."
and yet when hagrid was telling harry his history, he says voldermort, although he doesn''t like it
In the fifth book, when Harry, Ron and Hermione have a meeting in the Hog's Head, they invite along some students from hogwarts including Dennis Creevey, who couldn't actually have gone to Hogsmade in the first place because he was only in second year.
You can't go to Hogsmade until you are in third year. Also he probably didn't know enough magic at that stage to be as good as the other DA members.
In the harrypotter books 1,2and three the quiditch captain for the slytherin team(marcus flint) was mentioned as a sixth year in the first book. In the second book Marcus flint is in his final year at hogwarts. However in the third book when harry faces slytherin crabbe goyle Malfor and marcus flint try to scare harryby dressing up as dementor. ther are only 7 yars in hogwarts and marcus is still in the third when his final year was in the second book.
In book #3, it says that Percy got his top NEWTs and Fred and George scraped a handful of OWLs each, but in the fifth book, Harry said that he could expect some mail over the holidays, because they would be getting their OWL results in July. How come Fred and George got their OWL results at the end of June of their third year?
At the end of GoF; Harry rides the "horseless" carriages back to Hogsmeade station on his way to Kingscross. But, having witnessed Cedric die, he should have seen the Threstals pulling the carriages
in the second book in the chapter"Dobby's Reward"it says that Dobby dissappears with a final crack when we all know that you CANNOT apparate or disapperate in Hogwarts
in the 3rd book when harry has got a godfather he has not been chrisend
when harry was a baby he witnessed his mother die. shouldn't he see the thestrals before the fourth year. well we knwo he went in the boats in the 1st year. 2nd year he crashed into a tree with mr. weasleys car. but the third year..... he should have seen them
In Book5 before the OWLs Pavarti and Lavender made PENCIL cases race.But at Hogwarts you use quills and parchment.So why would they have pencil cases
in the fourth book J.K. typed sumething then put 'said moody' and she wrote this after everyone found out about the impersonater so she should have put 'said crouch'
In the first book, when JKR is describing Scabbers, she doesn't mention that he has a toe missing. This is not exactly a mistake, but I really think she should have mentioned it, as it now looks as if Scabbers lost his toe in book 3
in the fourth book the word pen was used when the wizards and witches only use quills not pens.
So i want to know what do u think ? is all of them really a mistakes or some of them are just misundersating ?! and please if u can tell us other mistakes that have been through the series which u have noticed and werent mentioned here ... i have many myself
