Perhaps Not

that's the usual saying of my calculus lecturer..
"Hmm.. Perhaps not.. Let's try again..."
lol

That's totally right..
Try again..
Things won't change unless you make an effort to do it...
Sometimes, things won't turn out as expected, or it doesn't seem as how others see..
That's why,
there's tomorrow, so that we can improve ourselves..

**back to homework...
too much slacking these days.. xP
