One week to go (6 days to be precise) with only 5 effective days to practice.
I will follow other candidate's advice to give myself a relaxing day before the exam. Thus I now only have 5 more days for the practice before the exam clock starts ticking.
Nervous??? Surprisingly no (???)
Does this mean that I am really ready? Because during my past study experiences, if I am nervous the score is good and while I am confident the score is bad.
But, that is for the pen-and-paper tests
I believe the practice exam would be different 
Anyway, today I felt something strange: my left eyes are acting differently. It feels like I have stared at the sun for prolonged period. Thus I felt there was a bright light blocking my left area.
Looks like I am physically tired, so I took a quick rest and I felt fresh immediately.
