There are 3 photos on her wall which means one for each year . I don’t know how US schools time this things so I’m guessing one for each year .Also judging from the fact that Equestria has lower gravity ,it stands to reason that time moves slower there then earth .Aether way it’s impossible to tell given that we there is no actual time measure system in Equestria other then Moon cycles which are subjective as all fuck since no one knows the duration of the days or the trajectory of the planet around it’s fucking sun or even how big the fucking planet is

@Telyna  
Where was it said she spent 4 years there? If you’re indicating the pictures in Celestia’s office, one could be from the Spring Fling. That would place her at around 2 years in the mirror.  
If you aren’t talking about the pictures, explain.

And still not one of you mentions how Applejack said to Applebloom that she was the last pony in her class to get her cutie mark ,or am I missing something here .Maybe Ponyville had a school with a morning shift and an evening one ,therefore most of them wouldn’t have met each other till a later stage in their lives, also camps are during the time witch schools are out for the summer ,therefore the home-schooling theory flies out the window .
 
The thing is we have incomplete data regarding the school and intellectual systems in Equestria ,also if Cadence in Shining are in their mid 20s it also means that Sunset Shimmer is around that age as well ……She was at least 17-20 years old when she went through the portal and spent 4 years there. Im not even touching the huge fucking hole in most of your theories with this one which makes Twilight even younger then anyone thinks.

@Background Pony  
Her ideas have spiraled wildly out of her control before. It isn’t entirely inaccurate.

@Aharon L’anglais  
“Super genius” may not be the best way to describe her, considering the character most closely associated with that phrase…  

@James Rye  
Twilight is a super genius. She could easily be the youngest of the girls with her intelligence.

@Mayojar77
 
Actually given that Twi has read complicated magic spell books at that point of the flash-back to prepare for her entry test I think she is older than RD who was only at flight camp at that time.  
After all reading is way more complicated than walking. And flying is like walking for pegasi. And given the stuff and how much Twi has read she could as old as AJ who has been shown to be old enough to be send off on her own to relatives.

@TexasUberAlles  
Actually, it was kind of over already.

@TheLoneLampman  
Oh COME ON, you scared them away! I was watching that trainwreck, man!

@TheLoneLampman  
Yes SRSLY! FF14 was down due to emergency maintenance what else was I suppose to do other then point out bad head-cannons?

@vilkas  
Quite simply, your evidence is based on outdated or even flawed information. For my argument to have lost any ground, it would have to have stopped existing, since your theory was based more on ‘there’s no evidence against it’ despite there being more than enough evidence against your theory.  
For one, Have you ever been to a high school where they call the first year there ‘high kindergarten’?  
Second, Pinkie’s farm wasn’t ‘just outside of Ponyville’, it’s a very long distance away from anything, seeing as nobody even has a clue what she’s talking about, meaning it’s in an isolated area. Isolated areas tend to not have enough reasoning to start a school, so it’s not unlikely for someone to be homeschooled there.  
Third, Applejack comes from an agricultural background, And her family evidently goes through hard times every now and again, so it’s very likely that Applejack was homeschooled due to financial constraints, and Applebloom wasn’t because they have much more money.  
As for the cutie marks=puberty thing, the only person who ever said it was Faust herself, and she does not actually write these things. Add to that, the wording of that statement sounded to me like it was only as important as puberty, not actually being puberty itself. And really, from a biological standpoint, having your physical development restricted by whether or not you know what you’re going to do with your life seems stupid.  
And as for your use of saying that Sweetie must have been younger than Twilight in “Cutie Mark Chronicles”, Twilight actually was trying to learn magic. Sweetie Belle couldn’t possibly care less. When teaching a child something, it’s far easier if the child actually wants to learn.  
And on top of all this, you equated my analogy as a racist comment, despite the only parts of the identities of the subjects being that one was from the United States of America and one was from Australia, and that they were both male, and that only the American one ever bothered to learn to use a gun. I did not in any way mention race. They could have been an African-American and a French-Australian. Hell, they could have been the inverse.  
TL;DR, your arguments and your ability to recognize different races are both hopelessly flawed.

@Mayojar77  
? please add context. without it just looks like your trying yo insult me… I’ve added my points on why I think the m6 attend school and countered yours with real life knowledge and things from the show. so please tell me where you think it fell in, else this just looks like a petty insult with nothing to back it up…

@vilkas  
If my arguments are losing ground, yours have slipped into the ocean.

@Mayojar77  
yes because animation errors never occur cough Derpy cough and yes the CM are for what there good at but as Faust says they are symbolism for puberty and how girls can be mean to late bloomers… I’ve noticed you dont comment on any of the other points only the cutie mark being a symbol for puberty… and you call me stupid your arguments starting to devolve you’re not countering my points or adding new points to yours your tossing insults at me… I feel your losing ground…

@vilkas  
Cutie Marks are not a ‘puberty analogue’. There are ponies seen in all stages of life that don’t have cutie marks. Sapphire Shores doesn’t have a cutie mark, and she’s a famous pop star. Greenhooves is a caretaker. Personally, I think it’s basically what they’re good at. Like they say it is in the show.  
And on top of that fallacy, you equate noting the prevalence of gun culture in America and the lack thereof in Australia as “racism”. I just simply cannot take you seriously if you’re stupid enough to believe that’s racism.

@Mayojar77  
how do you know Twi just started school as I said CM represent puberty in this world which would put the characters around 10-14 give or take this can be seen by Apple Bloom, and how she acts/ gets treated about her CM and Word of god as Faust said thats what she wanted them to represent. Why would a parent pay more money for a better education? do I really need to answer that? Almost every parent would send their kid to a better school if they could afford it. now on to AJ your saying why would her parents allow AJ to go visit her Aunt/uncle if she was inrolled in school right? well why would they allow a young kid to make the trip alone in the first place whether she had school or not but its not that hard to change schools so they could have sent word to the oranges to enroll her in Manehatten after all kids change schools all the time… and now onto Pinkie She acually doesnt say there was no one around. She even states she was on a rock farm outside of ponyville and going over the episode she never said she doesnt have friends she just says there was no talking or smiling on the farm for all we know she could have had tons of friends in ponyville. So your whole argument about pinkie is void… and lets not even go into that racist analogy

@vilkas  
No, you are simply ignoring logic.  
Why would any parent in their right mind allow a child who just started school to jump to a new school where they have to pay several times the current tuition fee? Because I’m pretty sure private schools are fucking expensive.  
Seeing as how Applebloom didn’t appear in Applejack’s flashback, it can be assumed at least her mother is still alive. Now, exactly how many parents would allow their child on a cross country trip to go visit relatives if said child was attending formal schooling?  
And your argument about Pinkie is that ‘they never explicitly say that she didn’t’, which is stupid since she actually does in fact say that there was noone else her age around except her sisters.  
And my analogy was based around the fact that only one of the two is really all that interested in learning how to do the thing.

@Mayojar77  
lol I’m missing the important points? how? your talking about they don’t attend school all because RD and Shy attend a camp during summer. If anything im hitting the important points your theory consists of AJ didnt talk about school in her CM story therefor she doesnt go to school. And Pinkie has no friends so she didnt attend school or Twilight got into a private school so she didnt have school before that… I’ve merrily shown how that thinking doesnt work. I just think you ran out of reasons for your head-cannon to stay afloat

@vilkas  
I get the feeling that you are missing every important point.

@Mayojar77  
just because she attended kindergarten doesn’t mean thats what she was going into… she could have taken it already maybe last year maybe 5 years before she applied for CSFGU. Remember Cutie marks are suppose to represent puberty which most likely would put them at 10-14 did you take kindergarten at 12? and again what relevance does AJ dropping out of her old school have in her cutie mark story? it should be implied she was changing schools because she was moving to Manehatten. or do you think aunt and uncle orange would home school her there too after all she never talked about the school in Manehatten so your logic should imply she never had plans to attend school in Manehatten. which would be wrong you don’t include irrelevant info in a story her dropping out or attending school was irrelevant to her Cutie mark story she didn’t get it because of school… I’m not sure what your getting at with Pinkie… my last point still stands she could have been a loner and not known how to make friends but still attended a school… Also quit being Raciest not all Americans know how to use guns I’d say about 80% don’t know how to use guns

@vilkas  
Remember how in Lesson Zero Twilight mentioned ‘Magic Kindergarten’? Now, why exactly would someone need tho go through Kindergarten of any kind if they are already old enough to be going to a summer camp?  
And Applejack never mentions the fact that she’s effectively dropping out of her grade school when she’s telling her story.  
And even gloomy people can make friends. They’re called ‘Goths’. Pinkie could make friends with the worms in the dirt if she was desperate enough.  
And as for using Sweetie as an example, you know that’s not actually applicable, right? Twilight was actually endeavoring to learn magic, and Sweetie just doesn’t seem interested. That’s like saying that an Australian man is younger than an American man because he doesn’t know how to use a gun.

@Mayojar77  
so just because you have no friends means you don’t attend school? there are humans who don’t have friends even though they attend public schools we usually call them loners. Also Rarity’s flashback was about Rarity if I’m telling you about how I found my passion and favorite hobby am I going to tell you about my friend joe who has nothing to do with the story? no I wouldn’t joe has nothing to do with what im telling you so why talk about him same with Rarity, AJ didn’t help her get her cutie mark so why would she talk about AJ? and where are you getting kindergarten? Twi applied for Celestias School for gifted Unicorns it doesnt ever tell you what grade you should think of Celestias school as a private school only open for those who are already good at magic and since twi could read quite well to learn the magic I would think she has gone to school before she attended CSFGU. P.S. sweetie is in school and it doesnt look like kindergarten but she still cant use magic

@vilkas  
First off, Pinkie asserts that she had no friends at the time she was at the rock farm, implying that there was no nearby school that she could have attended.  
As for Applejack, doesn’t it seem weird that in Rarity’s flashback she doesn’t mention Applejack at all, despite the fact that there’s literally one school in all of Ponyville? If Applejack attended the school, then Rarity would have at least known she was around.  
And, as for Twilight, Kindergarten is basically for five or six year olds, not for people who have finished an era of schooling.

@Mayojar77  
you do realize that we know the CMC go to school but 90% of the time we see them they are out of school. just because none of the m6 were in a school when we seen them doesn’t mean they didn’t attend after all the average student only goes to school for 7 hours a day usually getting out at 3 assuming its summer the sun wouldn’t set until 7-9 PM leaving a lot of time for Pinkie to do farm work though I think it should be obvious its summer break in the flash back with RD and shy at a camp and AJ going to Manehatten.
