Each tutorial is down the hall or down the hall and up one staircase from the lecture room. The basements of the three arts quad buildings (TSH, KTH, and CNH) are all connected and easy to navigate with a little practice.
Go with whatever tutorial you want, not the TSH one just because it's in the same building. They'll all be easy to get to, just check out the rooms before hand so you know the path to get between them
Also you'll have more time than you think. Your class will rarely go the full three hours.
LS 1A03 is a great class too btw
