WC=QC

I don't know where did I get this idea..perhaps, this is what people called serendipity...
Let's see ....Ms Winnee used to organize colloquium almost every semester, and she teaches most of the stat courses (last time).
Typically, most of the presenters are from stat courses...
Then, she wants students to present to her before they can even present in front of the students. lecturers, and some other people in the colloquium....
In a way, she's the quality controller (QC) of colloquium too!!!!
Don't you think so??? This is so interesting!!! And she tend to use WC to represent herself in course outline...that's where I the WC from...

In conclusion....

WC=QC
