Additional Mathematics

When a child reaches her sweet sixteen,
It's time the school did something to her study regime,
Oh boy, it won't be pretty,
Cause now you have 10 subjects to study.

If math alone wasn't enough,
I would have to say add math is super tough!
But all would start to change,
With Madam Cheng in the frame.

Chorus:
Biology, chemistry and physics,
They give me headaches,
But nothing can be worst than,
ADDITIONAL MATHEMATICS.

What is the square root of 625?
And what is my phone doing under my thigh?
Please teach me, guide me, make me understand,
So that i can get through this circumstance.

-Odd al.
