You may upload your presentation file using this form.
The file must be in pdf format. It should have a filename that is of the form: uinetid_ps#_q#.pdf, where uinetid is your official uinetid in lower case letters, and the #'s should be replaced by the number of the problem set, and the question your were assigned respectively. For PS3, the question # should be odd, that is those assign 7-8 should have "q7". You are free to use any text formatting system you want to prepare the pdf file, but eventually you will probably want to learn latex and for latex it is quite convenient to use beamer. You can google to find useful tutorials.
Files that are larger than 3Mbytes will be rejected.
