The football game against Lincoln occurs after the Christmas scenes. A regular high school football season would have been over by then.
When Brad is being fired in All-American Burger, the Coca-Cola clock on the background keeps shifting time out of sequence.
Spicoli ordered a double-cheese and sausage pizza for Mr. Hand's class, but when the box is opened there's only cheese on top.
The patch Damone puts on his Gremlin to cover the word "prick" is too small, yet there is no paint beyond it.
When Mr. Hand is asking Spicoli about his truancy, he writes, "I don't know," on the chalkboard. As he does this there is a shot of the class where Stacy is wearing a completely different outfit than in the rest of the scene. It is established that she is wearing a brown sweater, beige pants and a brown headband, but in this one shot she is wearing a red vest over a pink shirt.
When Stacey and Mark are at the restaurant, they order two refills of Coke while Mark stalls to get his wallet from Mike. There is not a waitress in the world that would leave their table that messy and not take back the finished glasses, plates and antipasto tray. Not necessarily true - plates had food left on them and he was trying to buy time so he might have asked her to leave them so they could finish.
When the girls get off work at the mall they are exiting through the mall itself. Store employees leave through the back doors of their shops. Depends on mall policy and layout- may not have been a back door or might have been on an upper floor.
When Jefferson's little brother is riding in his older brother's (Forest Whitaker) car with Jeff Spicoli, he asks "you seen the new Playboy? Bo Derek's tits!". Bo Derek last posed for Playboy in August 1981. Filming for this movie was in November & December of 1981 so that "new" playboy would have been three of four months old.
When Jeff Spicoli arrives at the school dance, he ducked underneath the balloons and flipped his hair. Sean Penn wore a fall, which is a wig only for the back. The front was his, but the back wasn't, so when his real bangs are in midair, the lining of the fall can be seen.
When Rat forgets his wallet, he calls Damone and asks him to borrow his mother's car to bring it to him, but later in the movie, he drives a Gremlin from the apartment he is also not supposed to have, clearly indicating it is his car. These two scenes are separated by several months, so it's entirely possible he could have bought the car in the interim.
Rat plays "Kashmir" from Led Zeppelin on his date with Stacy which is from Physical Graffiti, not Led Zeppelin IV. Despite numerous previous submissions, this is NOT a goof. A rock journalist like Cameron Crowe would never make this mistake. The producers weren't able to secure/license songs from Led Zeppelin IV but had access to Kashmir. From a character/in-universe standpoint, one could say Rat was clueless and played a song from the wrong album.
At one point, Brad claims he has to work before school. But this is during the part of the movie that he works at the seafood restaurant. No fast-food restaurant like this would be open early enough that someone has to work there "before school." One possibility is that the scene was originally meant to be put later in the film when he got the Mi-T Mart job. This theory is backed up in the alternate broadcast version where Hamilton is in a guidance counselor's office talking about his future and he says "I get up at 5:30 to go to work at Mi-T Mart, THEN I go to school, THEN I go back to Mi-T Mart!"
Stacy is giving change for a piece of pizza a customer is waiting for, while Ratner waits patiently behind waiting to ask her out, she says "$1.10 and you get $.5 cents back". For most coin combinations this is nonsense, but three quarters (75 cents) plus four dimes (40 cents) is $1.15 and would yield a nickel change.
The bikini top which Linda takes off during the dream sequence is fastened up front - when she enters the restroom looking for a Q-tip a few minutes later, her bikini top does not have the front fastener. This is a dream sequence, so this is allowable, and not a goof - Brad wanted it to open from the front in his dream.
Mr. Pizza Guy says Spicoli's pizza is a double cheese and sausage but there's no sausage on the pizza.
When the little kid wets his pants, Santa's knee is completely soaked but the kid's pants are dry.
During the "No shirt no shoes no dice" scene when the camera goes back to Spicoli saying no dice then laughing, the guy behind him is moving his mouth along with the words then laughs when Spicoli does.
During the fantasy interview, Sean Penn can be seen repeatedly looking down and to the side, picking up his lines from cue cards.
During the football game scene, it appears as if Ridgemont is celebrating an end-of-game victory, yet the scoreboard shows that it is only the second quarter.
Stacy collects payment for a tab of $1.10 and provides the customer with 5 cents in change. An apparent mistake in the script, however if the customer is using pocket change it is plausible that he gave Stacy 3 quarters and 4 dimes ($1.15) and received a nickle in change.
When Spicoli and his friends enter All American Burger and take their shirts off, Spicoli mouth is closed when he says "This one's on you dude".
When Brad drops Stacy off at the bowling alley, crew members can be seen reflected in the car door's window as she opens her door.
When the Pizza Guy knocks on the door, a crew member can be seen moving in the reflection of the glass.
When Spicoli jumps on stage to sing with the band at the dance, a camera and cameraman can be seen in the lower left part of the picture.
As Rat leaves Stacy's house at night, a crew members shadow can be seen moving on the overhang of the house in the upper right corner of the screen.
When Damone and Stacy are walking home from school, each can be seen with a lump under their shirts from wearing a wireless lavalier microphone.
After Spicoli trashes Jefferson's car, how does he drive it to Ridgemont High? It couldn't run with most of the front being completely crushed, and having a tow-truck bring it there would have exposed him.
When the robber hits the cookies off of the counter in the Mi-T-Mart, the boom can be seen moving in the window reflection.
As Brad is attempting to open the safe in the convenience store, the boom mic can be seen moving in the reflection of the window.
Mr. Hand tells the students that the Platt Amendment is an Amendment to the US Constitution and is vital in their daily lives. The Platt Amendment is neither a Constitutional Amendment nor is it important in Americans' daily lives. The Platt Amendment established Cuba as a US protectorate after the USA helped free Cuba from Spanish rule during the 1898 Spanish-American War. Furthermore, it was passed in 1901, not 1906 as he claims.
Outside the theater, Mark Ratner is informing patrons, "Smoking is upstairs to the left..." Clearly visible in the box office window behind Mike Damone is a "No Smoking" sign.
However, the 'no smoking' sign is referring to the lower level seats, which is precisely why Rat says smoking is "upstairs."

When Mr. Hand is giving the class a hard time about their scores on their quiz about the Platt Amendment, he says the amendment was introduced by Senator John Platt, that it passed in 1906, and that it was an amendment to the US Constitution. He trails off when he notices that Spicoli is absent, and starts talking about his generation's fascination with truancy.
The Platt Amendment was not a 1906 amendment to the US Constitution. It was an amendment to the 1901 Army Appropriations bill having to do with conditions for unilateral US intervention in Cuba. Its author was Connecticut Senator Oliver Platt, not John Platt, which Mr. Hand would know.

At the beginning, when the kids are buying the concert tickets, it is said the tickets normally would cost $12.50, so two would be $25. The tickets are sold for $20 each ($40 total), and he says he made $16, when actually he only made $15.
Stacy is ringing up a customer for a slice of pizza he bought. He hands her what appears to be a dollar bill and some change.
Stacy then says it's $1.10, and you get 5 cents back.
There is no way that she could give the customer 5 cents back based on the money he gave her.
If he gave her $1.25 the change is 10 cents.
He would have had to pay her with all coins to get 5 cents back: 3 quarters and 4 dimes would equal $1.15, which would give him 5 cents back.
