If you're talking about the "No true Scotswoman" quest I can help - You need to get cups from the teacher's desk, an eraser from the trash, the globe either next to the desk or on it (I forget), place the cups on the desk that can be interacted with an object, then challenge flora to guess where you put the eraser, use the globe on the basketball hoop, clean the bolt off on flora, interact with the bookshelf, then interact with the book you get from it, give the book to the other one (forgot her name), I also forget where you get the wrench but if you have it use it to open the window, go to the caf to get more haggis, then the gym to get a ladder to get back into the classroom. However, with the new update, you may not be able to pick up the ladder meaning you can't finish the quest. If I'm not referring to the right quest you'll have to be more specific when you ask "how do I escape from the classroom". Does that help?
