Getting Pumpkins and Tombstones:

During Halloween, you can get a bonus from finding and smashing all the pumpkins and tombstones scattered around. If you miss some, don't worry. In the next and last mission of the chapter, when you go into the school's basement, you can find the pumpkins you missed in the boiler room. Later on, after unlocking the preppie part of town, next to the asylum you can find a warehouse containing all the tombstones you missed as well.

Double your tickets:

If you finish photography class, you can get twice the tickets at the fair.

Get old bikes from shop:

After beating shop 5 you can still get the shop 4 bike even though you earned the shop 5 bike. To do so you will need to go in front of the preppies boxing club, then go to the right of the building. when you get to the right side of the building(make sure you are on some kind of bike) spin in a circle by holding the left joystick all the way to the right. After a while you will see a bike appear by the wall. it might take a couple of tries but after a while the blue bike from shop 4 will appear.
