Handing in of weekly/bi-weekly assignments can be done from any of the 3 studios.  Look on the Desktop for a link, in all caps, saying, "HAND IN ASSIGNMENTS HERE".  Inside this link you will find folder for each assignment (assignment_1, assignment_2, etc).  In most cases you should be handing in a WAVE audio file.  You must name the file with your netID for identification purposes.  I would recommend a more complete title such as:

120_a2_kme32-my_latest_tune.wav

The above format says the course number, the assignement number (a2 for assignment 2), my netID, and the title of the track.  Note the use of underscores and hyphens rather than spaces.  This is CRITICAL for tracks which will end up online.  I highly recommend getting used to filenames without spaces.

Assignments involving multiple files should be compiled into a single .zip archive to be handed in.  This is accomplished on either Mac OS or Windows by moving all desired files into a folder, right-clicking on said folder, and choosing "create Archive of ..." or comparable option.
