9-09-09 Update: Welcome Back!

To my students,

Welcome back to 2009-2010 School Year!

After the summer break, I am sure you're all eager to learn new stuffs so as to make yourself "smarter" and "wiser". The first step in all of this is to take control and be responsible for your own study/works. If you don't help yourself, your parents won't be able to help you, and your teachers won't be able to help you.

Be sure to bring notebook, pen, and the right state of mind for this coming year. We shall begin tomorrow.

Dr. Liu
