Hi, Several people have asked whether the labs are assessed and/or should be submitted. No, that is not required. The plan is that I will release (on the CITS2003 and CITS4407 lab pages) the proposed solutions to each lab, a week or two after the lab. While the labs are loosely tied to the lecture content, they can be done at you own pace. That said, you need to know that the labs exercise the sorts of skills you will need for your OSTS assignments. Cheers MichaelW
