Silent Hill f's School section is one of my favourite parts of the whole game. It brilliantly merges horror, action, and some fun puzzles together, so you get a taste of everything in this short section. With that said, the School puzzles in this part may throw a spanner in the works, so here's a guide for getting you through this section, girl locker codes and all.
Arriving at the school with Shu and Rinko, you go to the back gate, which leads to a mountain pass—your supposed escape route from the horror that is encroaching on Ebisugaoka—only to find that it's locked. Instead of hopping over this shoulder-high obstacle, which is what I would've done, Hinako and her friends opt to enter the school in search of the key.
