There are important and key differences between "study for the test", "study for the knowledge", "passing the test", and "demonstrating your knowledge". For example: My wife can pass multiple-choice tests with little of the knowledge [she freely admits this]. She had to study her head off for a recent test in a subject she knew little about, because the test was only partially multiple-choice. She ended up passing, yet if I were cruel -- this subject is something I enjoy learning about on my own -- I could snap-test her at will to see if she retained anything for any given time period after the test, and she could likewise do so for herself in everyday life.
