Goofs

Continuity 

The rear right window during the argument about the double burger.

Audio/visual unsynchronised 

When Will is in court for assaulting an officer, he is talking and the opposing lawyer stands up and says "your honor" but his mouth never moves.
When Profr. Lambeau is looking at Sean through the glass in the door in his classroom, his mouth doesn't match what he is saying.

Boom mic visible 

When Will is given his new car, the microphone can be seen reflected in the window at the right bottom side of the screen

Character error 

When in court for his assault on a police officer, Will begins to quote Henry Ward Beecher's "Prayers from the Plymouth Pulpit" and dates it to 1887. It was actually published in 1867. Henry Ward Beecher died in 1887.
At the scene in the Harvard bar before we meet Minnie Driver's character, Ben Affleck orders a "pitcher of the bar's finest lager". The bartender returns with three bottled beers for Affleck, who says nothing about it.

Continuity

After Will is released from jail and is riding the subway, the scars from his fight disappear, only to reappear in the next scene.
When Will and Skylar are at the outdoor cafe near Harvard Square talking about the complicity of Organic Chemistry, her front shots show her hair on her shoulders, and the rear shots show her hair in the middle of her back.

When Will burns his proof of a problem and Gerald puts it out, the amount of burn damage changes from almost completely destroyed (when Gerald first extinguishes the flames) to minimally burnt (near the end of the scene), and various other degrees in between.

At the end after Will leaves and Chuckie goes to pick him up and realizes he's not there, while he's walking back to the car he tells the other guys that Will's not there. However, it can be seen from his lip movements that this is not what he actually says.

When Chuckie is having the conversation with Will about how he wishes one day Will wouldn't be home when he comes to pick him up, he finishes the scene with a sip of beer from a can. The can is in his right hand as he takes the sip, but in the next shot as he lowers the can from his lips, it has miraculously jumped to his left hand.

Crew or equipment visible 

Near the ending during the scene where Chuckie is at Will's house to pick him up, as Morgan gets out of the back seat of the car to change and sit in Will's old seat, while he's climbing into the passenger seat at the bottom left hand corner of the screen you can see a crew member with a red hat on watching from the sidelines.

Factual errors 

The combinatorial problems and solutions shown on blackboards are elementary ones, not the sort that would occupy a Fields medalist for years.
When Professor Lambeau is interrupted at the alumni cocktail reception, the alumni wearing the red jackets are all too young to be wearing the he "Artillery" Red jacket, which is the MIT 50-year alumnus jacket.
The closing credits thank "the State of Massachusetts". Massachusetts is actually referred to as "the Commonwealth of Massachusetts".

Incorrectly regarded as goofs 

When Will is seen driving to Stanford during the closing credits, the sign on a bridge over the highway says "Prospect St., Stockbridge", which points to him being on Rt. 90 west (MassPike). This means Will was taking an 18-mile/1-hour detour through upstate NY and Cleveland, Ohio, as the faster way to go (according to Google Maps) is via Rt. 84 south through Connecticut. However, prior to Google Maps (and indeed even today), most people driving from Boston to San Francisco take the direct route of I-90 to Chicago and then I-80 from there. In spite of Google Maps, due to higher speed limits, Will's route is actually the faster route.

Plot holes 

While at the race track, Skylar, while rooting on her dog, mentions that it is winning the race. However, the camera cuts to the race and the "2" dog overtakes the leader and wins. She then states how happy she is that she won.

Revealing mistakes 

When Sean tells Will about how his wife used to fart all the time, even in her sleep, everybody is laughing. Even the cameraman. The camera starts bobbing up and down at two very funny moments during that dialogue.
In the scene where Skylar and Will are sitting at a table with the chess players behind them, the white noise in the background of the shot lessens for Will's line "and I can't play the piano" and the intensifies again afterwards. If you listen closely, you can tell that the one line is a voice over.
The person at the bar being served looks at the camera.
