Lab 2 and onwards should be submitted by visiting the 447 submission site. Your submission must meet the following requirements:

• .zip format only
• no subdirectories - to test whether your .zip uses subdirectories, extract your .zip to an empty folder on your computer. If the empty folder contains only normal files (and no folders/directories) then your .zip is okay.

All labs (except lab #1) must be turned in before the end of the 6th day after that recitation. For example, if your recitation is on Tuesday then the 6th day after Tuesday is the following Monday. In this case, you should turn in your labs before the midnight that causes Monday to become Tuesday.
