As you can see from the Marauder's Map (seen in the end credits of "Prisoner of Azkaban") certain elements of the student body are clearly up to naughtiness.
That being said, the creator of the end-credits is adamant that they're not having sex.
"Maybe it was meant to be Harry, but we've all been kids, we've all
been in school and stuff ... It was just ...
I don't think he chose "Dumbledore" as his password. He was an accomplished double agent, and would have chosen a suitable password that would avoid arousing suspicion from either side.
There are a few potential explanations:
It wasn't the password at all
We know from Order of the Phoenix that the gargoyle controlling access to the Headmaster's office has ...
The books mainly focus on Harry, Ron, and Hermione (with occasional dalliances towards other students, primarily when they interact with the main trio). They don't really pair up much with anyone in the series. Hermione's daliance with Victor Krum isn't implied to be sexual, just romantic, and takes place largely off-screen. Harry doesn't pursue anything ...
Your House can represent traits you value, not necessarily have.
This is a good explanation for all the Sortings that that don't seem to match up with the student's traits. Peter Pettigrew could have been a Gryffindor because he wanted to be brave, not because he was. Although he did develop courage later on, unlike Pettigrew, the same thing could be said ...
Out of universe, the answer is - as it usually is - that JKR is bad at maths. She likely didn't consider the kind of workload or number of lessons that would be required for there to only be a single teacher per subject.
However, let's see if we can make it work in-universe.
You stated in the question that there are seven years split between four Houses, ...
You can always fit in a Hogwart House.
The houses don't put you where you have your best traits, but what traits you value more. That's why Hermione and Neville were put in Griffindor, for example: Hermione would be more a Ravenclaw and Neville a Hufflepuff, but both of them valued bravery more than anything else. Not being wise or intelligent is not a "NO" ...
The writer of this Muggle article is ascribing Muggle values to the wizarding world.
The Wizarding world generally seems to accept danger far more readily then the muggle world does, a tournament is held that involves putting students in danger fighting Dragons, their loved ones are captured. They engage in a sport that sees children fly broomsticks at ...
There's no evidence that the library was badly organised. In every instance when students need information on a specific, known subject, they're able to easily find the book(s) they need on that topic.
The issue in Philosopher's Stone is that the problem they're trying to solve isn't one that any system of classifying or organising books would assist in ...
There are lots of fantasy works where sex is totally ignored, just because it's something natural that has nothing to do with the main argument. The same way, authors usually don't explain you when their heroes go to the restroom and how much time they spend there.
The fact that HP novels are set on a college with lots of teenagers could seem like an excuse ...
The "Werewolves" in the Forest are Actually Highly Intelligent Regular Wolves
This is from the Pottermore entry on werewolves:
One curious feature of the condition is that if two werewolves meet
and mate at the full moon (a highly unlikely contingency which is
known to have occurred only twice) the result of the mating will be
wolf cubs which ...
I doubt there's any single reason, but if pressed for a one-sentence summary I'd say that, on the balance, Malfoy's Hogwarts experience wasn't actually very positive. At the very least, it wouldn't have felt that way to him.
His last two years were quite difficult
His sixth year was an intensely stressful experience, which at one point led him to break ...
JKR's tweets are usually inspired from some form of intoxication.
Her tweets are not to be considered Primary Canon especially when they seem completely facetious, and completely contradict the books. She is a real person first, and an author second or third (she is also a mother (might be 2nd who knows)) so statements that seem funny, and don’t correlate ...
In general it is not allowed but finally it comes down to who is running the school.
Dumbledore was against it:
Professor Umbridge seized Marietta, pulled her round to face her and began shaking her very hard. A split second later Dumbledore was on his feet, his wand raised; Kingsley started forwards and Umbridge leapt back from Marietta, waving her ...
The evidence points that there were no restrictions or preventative spells keeping people from flying into and out of Hogwarts till year 6.
‘There are all sorts of enchantments on it, to stop
people entering by stealth. You can’t just Apparate in here.And I’d
like to see the disguise that could fool those Dementors. They’re
Since Harry was from a wizard family, the Ministry would presume his guardians, knowing about the magical world, would have told him.
Hogwarts sends officials to notify wizards born to Muggles, who would not have known about the wizarding world prior to their visit. Harry had two wizard parents, and the Dursleys did know about the magical world. The ...
Hagrid was employed as Gamekeeper and Keeper of Keys and Grounds of Hogwarts (even when he became a professor, he retained these jobs).
If you are a non-British guy, you might have trouble understanding these designations. From Wikipedia page of Gamekeeper:
A gamekeeper (often abbreviated to keeper) is a person who manages an area of countryside to make ...
Dumbledore was known to have failed to stand up to his friend.
We don't really know about that when Dumbledore makes his speech, but hind sight makes this quote resonate all the more.
Dumbledore raised his hand. The room gradually fell silent. "There are all kinds of courage," said Dumbledore, smiling.
"It takes a great deal of bravery to stand up ...
I don't think it's really as complicated as some of the other answers (and comments) suggest. The British, by and large, consider the secular celebration of Christmas to be part of their cultural tradition; the fact that some people celebrate it as a religious holiday has always been perfectly acceptable, of course, but was not traditionally considered a ...
Hogwarts is their home. The kids are (mostly) protected by being told to keep away from the animals.
Many of the creatures in question considered Hogwarts to be their home, just as much as any of the children did.
"What are you doing in our Forest?" bellowed the hard-faced grey centaur Harry and Hermione had seen on their last trip into the Forest. "Why ...
Parents can send letters by normal post.
“You didn’t think it was such a freak’s school when you wrote to the head- master and begged him to take you.”
Petunia turned scarlet.
“Beg? I didn’t beg!”
“I saw his reply. It was very kind.”
“You shouldn’t have read—” whispered Petunia, “that was my private—how could you—?”
Lily gave ...
No. As ever, the movies suck.
First and foremost, Dumbledore would never allow this. Observe his reaction in Book 5, when Umbridge touches a student.
Professor Umbridge seized Marietta, pulled her round to face her and
began shaking her very hard.
A split second later Dumbledore was on
his feet, his wand raised; Kingsley started forwards and ...
Not every member of the Slytherin house has gone bad and neither has every bad wizard been in Slytherin.
Here’s a little-known fact that the other three houses don’t bring up much: Merlin was a Slytherin. Yes, Merlin himself, the most famous wizard in history! He learned all he knew in this very house!
Quote from Pottermore, Slytherin ...
For a castle so well protected by ancient charms, there are many ways to get in!

As seen in the book Harry Potter and the Philosopher's Stone, Hogwarts has a school song.
Hogwarts, Hogwarts, Hoggy Warty Hogwarts,
Teach us something please,
Whether we be old and bald
Or young with scabby knees,
Our heads could do with filling
With some interesting stuff,
For now they’re bare and full of air,
Dead flies and bits of fluff,
Modern-style toilets were only added to Hogwarts during the 18th century:
When first created, the Chamber was accessed through a concealed trapdoor and a series of magical tunnels. However, when Hogwarts’ plumbing became more elaborate in the eighteenth century (this was a rare instance of wizards copying Muggles, because hitherto they simply relieved ...
When they were still alive, they each chose their house members.
When the Founders were still alive, they had all chosen the students who’d be in their house themselves - the Sorting Hat was created to keep their houses’ values intact when they were dead and couldn’t choose, but when they were alive they’d chosen their own favorites for their houses.
Can students drop out of Hogwarts?
Yes. At least up until HP and the Deathly Hallows, when going to Hogwarts is made compulsory by Voldemort's regime. As Lupin tells us:
“Attendance is now compulsory for every young witch and wizard,” he replied. “That was announced yesterday. It’s a change, because it was never obligatory before. Of course, nearly every ...
The Chamber of Secrets was described as being far below the school. Likely deeper than the dungeons:
It was like rushing down an endless, slimy, dark slide. He could see more pipes branching off in all directions, but none as large as theirs, which twisted and turned, sloping steeply downwards, and he knew that he was falling deeper below the school than ...
No, it doesn't look like it.
From Pottermore, we see that the Sorting Hat is very stubborn about sticking to the decisions it arrives at. It seems that it's impossible to protest that the Sorting Hat got the decision wrong and to ask it to reconsider.
The Sorting Hat is notorious for refusing to admit it has made a mistake in its sorting of a student. On ...
What if they can’t afford to go?
I don’t recall any mention of school fees in the books. With regard to school supplies, see Dumbledore’s visit to a young Tom Riddle:
“That is easily remedied,” said Dumbledore, drawing a leather money-pouch from his pocket. “There is a fund at Hogwarts for those who require assistance to buy books and robes. You might ...
