  1.  @Peter_1986  That's absolutely right and I would also suggest that it's better not to use it in tests/exams anything you haven't been taught in class. The examiners will probably mark you down even if you do explain clearly what you mean as they're only interested in knowing that you can use what is in the syllabus.
