From Dumb to Smart

It's kinda funny it is,
Was never really a wiz,
But now that's how it is!

I could have gone for less,
My brain could be a mess,
Now way I want the best!

When once I had no heart,
I just was not too smart,
Yet now I work so hard.

I make my way to heights,
See wins with every fight,
I get my answers right!

One day I'll win that crown,
Graduate top-in-town,
No one will pull me down!
