Most of my students passed the final exam swimmingly while a few of them failed it.
For those lucky dogs, I hope you continue to work harder and never take any chance in exams.
For those "unlucky ones", I hope you develop a good attitude toward tests. The purpose of a test is to show what you have learned about a subject. The world won't end if you don't pass a test. So don't get overly worried.
Tests do more than just provide grades. They let you know what you need to study more, and help make your new knowlegde permanent.
This is what a test is for. I wish all of you can get the meaning of it.
