Of course, it is very important to be sober when you take an exam. Many worthwhile careers in the street-cleansing, fruit-picking and subway-guitar-playing industries have been founded on a lack of understanding of this simple fact.
Interpretation
Being sober during exams is crucial for success, as ignorance can lead to limited career opportunities.
This quote from Terry Pratchett humorously emphasizes the importance of being sober and alert during examinations. By alluding to unusual careers that might emerge from a lack of understanding regarding this fact, Pratchett cleverly points out that poor decision-making can have serious consequences, especially when it comes to one's future and career choices.
In practice
In a light-hearted speech about preparing for exams, one could use this quote to emphasize the importance of focus.
And then Jack chopped down what was the world's last beanstalk, adding murder and ecological terrorism to the theft, enticement, and trespass charges already mentioned, and all the giant's children didn't have a daddy anymore.

And lots of other people. But everyone apart from them. It's a very enlightened civilization.

Any fool could be a witch with a runic knife, but it took skill to be one with an apple corer.
People look down on stuff like geography and meteorology, and not only because they're standing on one and being soaked by the other. They don't look quite like real science. But geography is only physics slowed down and with a few trees stuck on it, and meteorology is full of excitingly fashionable chaos and complexity. And summer isn't a time. It's a place as well. Summer is a moving creature and likes to go south for the winter.
Laughter is a force for democracy.
There is nothing funny about Halloween. This sarcastic festival reflects, rather, an infernal demand for revenge by children on the adult world.
And when we take ourselves too seriously, we are grim about the brothers and sisters, especially the dissenting ones, and there will be no health in us and no healing humor.
Humor can be dissected as a frog can, but the thing dies in the process and the innards are discouraging to any but the pure scientific mind.
