Select controller:Endless Summer isn't really part of the plot - it's just an open-ended scenario wherein you can finish any classes you didn't manage to graduate from before the story ended, and do any optional missions, races or jobs you missed out on.
The Diary (optional)
- Starts: Outside Bullworth Academy Girls' Dorm, 7pm – 11pm
Beatrice's diary has been confiscated by the maths teacher, Mr. Hattrick. Jimmy's not too concerned by the fact, until Beatrice reveals that large parts of the diary are about him, detailing their fictional romance. With that in mind, Jimmy makes a deal to get the diary back.
Beatrice reckons that the diary will still be in Hattrick's desk, so you're going to have to get into the school without being spotted by the prefects.
Head around to the south side of the school building, and you'll find a ledge that you can climb up. From there, walk over to the yellow circle on the ground and press 
to climb onto the scaffolding. Move up to the top with 
, and you'll be outside a window on the upstairs balcony. Use to get inside.
Inside the school, keep an eye out for prefects, as you are trespassing already. Their field of vision will be visible on the radar, so jump into a locker or trashcan to avoid them if needs be. The maths room is to the left of your entry point, but when Jimmy tries the door he finds it's locked.
The next point of call is the staff room, on the ground floor. Again, watch out for prefects on your way down — but if you make it into the staff room they can't follow you. Still, it's better not to have them hanging around when you're on your way out.
There's a desk in the far corner from the door; press and Jimmy will search through the drawers to find Beatrice's diary. You'll be treated with a two-page spread of the diary's contents; press to exit and continue with the mission.
Leaving the staff room, you're free to exit the building any way you please. One of the back doors is fairly close by, but leaving through the main door might be easier depending where the prefects are.
Head back to the girls' dorm and give the diary to Beatrice to complete the mission.
Character Sheets (optional)
- Starts: Bullworth Academy Library
Melvin's character sheets have been stolen, and it's looking like his Grottos & Gremlins session tonight is doomed. Jimmy might be able to help, though — Melvin offers to give you ten groats (dollars) and a pick of his wenches should you return the sheets.
The character sheets are in the possession of four groups of bullies around the campus. The closest group is to the south side of the library — hop over the wall and you'll find Trent and a friend. They offer you a game of "Roshambone", a game of "I'll kick you in the nuts, then you kick me", then start the game while you're not ready — tap to get up. They'll run off and leave the sheet lying. You can let them go and grab the sheet, or show them who's boss by beating the crap out of them.
Next, head towards the main school building, but before you pass through the archway entrance to the library, you should see a bully leaning against the wall to the right. If you try to pursue him, he'll drop some marbles, so take out your slingshot and shoot him from a distance. When he's out for the count, grab the sheet he drops.
The next closest is beside the boys' dorm — you can hop over the wall for a shortcut, or take the long way round. Again, using the slingshot to take him out from a distance is the safest tactic, although if you want to get hands-on it's not too difficult either.
The last one is by the autoshop. You can use the slingshot again, or take him on mano a mano; either way you'll get the sheet. Return all four to Melvin for your reward, minus the promised wenches
Panty Raid (optional)
- Starts: Come Hither, Bullworth Town, after 7pm
Jimmy catches the gym teacher Mr. Burton leaving the Come Hither adult store, and in an attempt to keep his feeble excuses sounding legit, Burton asks Jimmy to retrieve some "laundry" from the girls' dorm for him.
You can catch a bus to get back to the school, or just cycle/skate back if you prefer; there's no time limit (although if you're out after curfew it makes things more difficult).
Head around to the north side of the girls' dorms and you'll find some scaffolding. Press to grab a hold and use to climb up. At the top, head through the open window into the attic of the dorms.
Inside, use 
to crouch; if you run standing up you'll be heard by Mrs. Peabody. The five pairs of panties you're looking for are marked on the radar as 
— they're all on the floor below you, so head to the stairs at the far end and they'll change to 
.
As you move down, the authority icon will change to show you Mrs. Peabody's field of vision — if she sees you, you've pretty much failed the mission, unless you're very lucky in escaping from the dorms. Fortunately, all of the dorm rooms have a wardrobe in them that you can use as cover. She'll also move downstairs eventually, although she will come back after a while.
First things first, head to the bottom of the stairs and hide in the wardrobe there until you see Mrs. Peabody head into one of the other rooms. When she's out of the way, run across the corridor (open the other room's door if you need to) and pick up the panties on the floor. If you need to, jump into the wardrobe here for a short time.
Next, go into the next room along on the other side of the corridor, and from there into the bathrooms. Be careful around the showers; if you get too close to them, you'll be seen and kicked out of the dorms. You can hide here in the trashcan, if Peabody starts getting too close.
If Peabody's upstairs at this point it's safer to stay put; she tends to hang around at this end of the corridor.
When the coast's clear, move into the next room and then the last one. As soon as you pick up the last pair, one of the little kids will spot you and in the commotion someone pulls the fire alarm.
To get out quickly, jump over the railings at the top of the stairs and turn around immediately. Take a left and run to the end of the corridor — you should spot the emergency exit. You'll find yourself outside, but don't assume you're in the clear just yet.
Jump up beside the apple tree ahead of you, and wait here until your trouble meter lowers if you need to — especially if you're out after curfew, in which case you'll also have to watch out for prefects at this stage.
Mr. Burton is waiting for the laundry at the front gates; you can either head straight out the main entrance or take the long way around through the carpark exit if you're wanted too much.
Approach Burton and you'll finish the mission.
The Collector (optional) Scholarship Edition only
- Starts: New Conventry, Blue Skies Estate
Stealing bikes can be a pain but it can be done. Simply use the slingshot to take down the adults and townies but watch out for police. Get away until the red meter goes down. Make sure the bike you steal goes to his garage marked on the map. You can only steal bikes that are marked on your map.
Letterbox Armageddon (optional) Scholarship Edition only
- Starts: New Conventry, Blue Skies Estate
This is a simple task of smashing letterboxes. You could also do it without the bike but you need to be quick with the timer counting down. Also follow the path and letterboxes that are marked to make it easier to finish the mission.
