After all is said and done, more is said than done.

By the time a man realizes that maybe his father was right, he usually has a son who thinks he’s wrong.

Sure, we'll go all confident.

Man, we solved all the papers from 2000-2009 in school, and I filled all my booklet.
That was like a few months back.
Now I feel I don't remember anything.
And since the booklet is checked and marked, I can't even solve the papers myself again, so can't check if I know anything.

I don't know what to do. :S

I should revise all the tests once again, and look through the pp.
