These maps show each floor of the school and where different subjects can be found. Lagan is a big school, and we know students might get lost - especially in the first few days and weeks!
On your timetable, you will have a room code for each class - for example, you might have English in F29. The letter tells you what floor your classroom is on, and the number tells you where you have to go on that floor (the numbers start at 01 at the front of the school and go up as you walk round in a loop)
Room codes starting with F are on the First Floor
Room codes starting with G are on the Ground Floor
Room codes starting with L are on the Lower Ground Floor
Room codes starting with P are at the bottom, at the same level as the sports pitches - so we call this the Pitch Level.
