The easiest ways to find NotreDame High School are:

-From Hillhead tube. Walk up Byres Rd towards Safeway, turn left into Observatory Rd, follow this until it forks, take the left fork up to the school.

or alternatively

-From Gt. Western Rd. Turn off at Kirklee traffic lights to the South, then turn left into Horselethill Rd, follow this until it forks, take the right fork up the hill to the school.

Classes and workshops are usually in the assembly hall which as you go in the main entrance is straight in front of you. Sometimes however they are in a dinning room which is straight along the corridor to your left, down the stairs and left again throught the double doors. Ask the Janitor if you're not sure.
