I just added this course yesterday so I was hoping someone could give me a brief overview of the 1st 2 classes. Are lectures posted anywhere? Will the course material be on avenue?

the outline and the first 3 lectures are already posted on a2l
if you read the corresponding section in the textbook, you'll be fine.
we do have an assignment.. but thats due in october and he said he will talk about it more later
make you sure attend tutorials (which start this week)
there's also no exam in this course.. so study well for the tests
