The only serious exam in the exact sciences is physics. I'm taking computer science and algebra, and it's too easy.

And did you pass computer science? :)
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
