Intentionally he will do all this.

Unintentionally he will do far more than this.

As he wishes his examination to be a test and not a mere formality, as he wishes to sift the examinees and not to set the seal of approval on all of them indiscriminately, he will take care that some at least of his questions are different from what the teacher might expect them to be.

Also, as he is himself a rational being, he will probably endeavour to test intelligence as well as memory; and, with this end in view, he will set questions, the precise nature of which it will be difficult for the teacher to forecast.

But the teacher will make a practice of studying the questions set in the periodical examinations and of preparing his pupils accordingly, equipping them (if he is an expert at his work) with a stock of superficial intelligence as well as of information, and putting them up to whatever knacks, tricks, and dodges will enable them to show to advantage on the examination day.
