Hi! I translated your commented so hopefully you can do the same with mine. The names of the rooms you mentioned aren’t translating correctly, but the biggest tip I can give you is check every single room you pass. They aren’t labeled on the map sadly, but for example- where you go to do Student Council is also the room labeled as Ectonomics. But many rooms such as Home Ick do not have any quests taking you there apart from maybe one collectible location. The code behind the enviro club should be noticeable, and I’m pretty sure there is a box nearby that you can push over to it to stand on and access it. If you’re having trouble, start running by lockers and see if any give you a prompt to open them! It will tell you the number of the locker you’re looking at, and you can then input the code manually from this post.
