I got 153, 154, 156, 157, 158 by being in dorm room in front of computer on Saturday and Monday for a couple weeks in a row, buying the sound recorder, visiting the library to talk to glasses girl and talking to glasses girl at the pool on the weekend, more time in dorm room on Monday, library over and over for English teacher scene, library over and over for drama teacher scene.
I am missing 155 and I don't know how to trigger it. Does anyone know how to do 155?
