Dear Calculus,

I cannot believe you

I try my very best and you let me down

After all that we have been through

With your derivatives and integrals

I just cannot keep up

No matter how much time I spend with you

It does not do much to improve my luck

So here we are, the final weeks

I never thought they would come

As I sit here at my desk 

And begin to feel glum

Calculus, I apologize

but I will not be sad to see you go

I worked so hard for four long months

and all you've done is make me feel so low
