Hi All,
Just thought I'd let you know no more about the grading of the mini-project.
In general, don't worry too much about the grading. We realize that students
are coming from different backgrounds. In addition, we also know that it can
be tough dealing with experimental software at times. Hope you will bear
with us and we appreciate your efforts in catching bugs, etc.
The primary goal of the mini-project was to familiarize you with the
infrastructure available for your project (so that you can make good project
proposals) and to provide context for the lectures. We will largely be
considering your effort just as much as your end results in the grading ;-)
Srini
