Up to par
I took DMM lesson at 11:00 a.m.
There was a lot of static in Skype line because the signals was very weak. So, I sometimes couldn't hear what my teacher said.
Anyway, the theme of the lesson is 'health'.
Today's new word is "I was not feeling up to par".
The 'up to par' means 'as good as the standard' referring to http://idioms.thefreedictionary.com/up+to+par.
