A Message from Ms. Chor:
"I was surprised that most of you have trouble finishing your test last Friday. Practice makes perfect, and without practising regularly, you will feel less confident and more anxious when writing a test. Anxiety would affect your performance on a test. I hope you will all reflect on your last test experience and make new plans on how to study and review for Unit 3 which will be posted by the end of March 10. I am busy with my assignment as I am taking an additonal qualification course now. After it's done this afternoon, I will work on Section 3.1. Sorry for the inconvenience."
