Go straight to Information Overload
The Owheo Building houses all the Computer Science people. The ground floor contains all the undergraduate labs; COMP112 uses Lab A and COMP150 uses Lab C. The first floor houses the System Administrators and the postgraduate research labs. The top floor is home to the lecturers.
Just a short walk toward campus are the Archway West lecture theaters. Built in the 1970's nuclear fallout shelter style they are in stark contrast to the original Archway building which, coincidentally, was the main Computer Science building for many years. The Archway West theater complex is noted for its peculiar numbering system and difficulty to navigate. I guarantee that you will have to do a least one complete circuit of the building to find the theater you want and when you leave you will not leave by the door you entered and will be facing some completely unfamiliar part of the University.
In you CS labs you will be lead through a series of exercises designed to give you practical experience in web page development (COMP112) and programming with Python (COMP150). In both papers you are scheduled to 2 two-hour labs per week. You should definitely attend these sessions. If you want to come along to other sessions then please feel free, if there is a spare seat you are welcome to it. Please be aware though that seating priority is given to those scheduled for that particular session. The COMP112 laboratory times are given below.
Lectures serve a number of important functions in a course. They are not, as some may think, just the random thoughts that occur to the lecturer on the day but are developed very carefully alongside the labs so that labs and lectures both support each other both providing relevant information at the moment when it is needed. One very important function of the lectures is to provide a pace for the course. That is they let students know where they should be in the course at any particular moment.
