No not necessarily. Some lectures and tutorials can be upper campus while some can be lower campus. Do you know the location of the two classes you mentioned? If so I will let you know how far apart they are from one another.
Just remember to avoid classes between upper and lower campus. I used to have back to back tutorials between these two places and I swear to god I'll never select back to back classes between upper and lower campus again.
Especially when you have exam in the second tutorial that means you have to rush from one end of the campus to the other end.
