When Harriet is taking the "dirty call", it is clear she is using a school phone. However, in the next scene, when we see the fliers in the phonebox, the contact number begins with "07", the digits of a mobile phone number.

During Poppy's date with Freddy, when she's driving the car, you can see a strip of blonde hair. But, earlier in the film, Poppy and her friends are seen at a hair salon, and she has her hair dyed dark brown. Yet this is never seen again at any other time.

On the website of Abbey Mount school it says it admits boarders from the ages of 11-17. During the credits, the first thing that comes up is a workbook belonging to Poppy and you see that she is supposed to be in Lower Sixth. Since, if they have Lower Sixth they must have an Upper Sixth then Abbey Mount would admit girls from 11-18 / 11-19.

When Molly is making her peanut butter and jelly sandwich, she has a blue top with a pony on it. But when we see her again in the upstairs landing she is wearing a blue shirt.

Near the end, when Poppy is talking to her father, the hair across her right ear moves between shots.

In the school dance scene, Harriet quotes the movie Pride & Prejudice (2005), saying "You may only call me Mrs Darcy when you are completely, perfectly, incandescently happy." This quote, however, is from a final additional scene of the film which was included only with the US release to satisfy the US audience with "extra schmaltz". As she is from the UK, Harriet wouldn't have seen this version of the film, and so wouldn't have known this quote.

Kiki says "[she] was able to access the keystroke order of the root file to find out who was logged on" to the computer used to send the fake emails.

However, on an average computer there is no such thing as a 'root file' (only a root folder or user); keystroke logging is not standard and is usually done using an installed program (or by malware or a virus); and logins would generally be recorded in the system event viewer (although this usually has to be enabled first).

Mr. Nellist is DJing with two turntables but he does not have a mixer. It is not possible to DJ with two turntables without some kind of mixer (or at least some way to adjust the volume).

In the scene where Kate does Drippy's eyebrows, the matron calls lights out. Much to her roommates' dismay, she gets on her computer and discovers there is no wifi. However, after the lights go out, but before she gets on her computer, you can clearly see the blue light (the light comes from the screen of her computer), as though her computer is already open.

When Freddie drops his car keys, instead of simply bending down to pick them up, he gets down on his hands and knees with his face inches from the ground. Not really the correct way to pick up keys.

All websites (including Google itself) all say Wild Child has a run time of 2h04m but all websites with the movie only have the movie with a run time of 1h34m, the extra 30 minutes is important to the movie because it shows Poppy being more rebellious and her friendship growing more with her dorm mates. You can see small clips of the missing section within the extended trailer on YouTube.

Kate and the others tell Poppy that Freddie got caught with a girl in "the third grade". British schools refer to "years" not "grades".

On Poppy's first day at lunch, she tells her dorm mates she can't eat the food because she is "pescetarian Monday through Wednesday, fruitarian Thursday through Sunday and vegetarian ALWAYS". This isn't possible as pescetarian's eat fish and vegetarians don't. The two were mixed up.

When Drippy does not know the meaning of the word 'ergo', Mr. Nellist calls her a Luddite, presumably using the word to imply that she is ignorant.

However, colloquially, a Luddite is a person who is opposed to new technology or ways of working or is someone who resists progress. So it is, in fact, Mr. Nellist who is the ignorant one in this case.

When someone hands Poppy some chocolate on her first day she says 'Ew! That's carbs and sugar.' However, sugar is a carbohydrate.
