Revision.

I may have mused once or twice before that the English language is a funny old thing.  An example: about ten years ago, when I first started taking viticulture classes at Napa Valley College, I happened to mention to Vinomaker that I was revising for an exam.  "You are changing something?" he asked.  Pardon?  Americans generally use the word revision in the context of altering something.  Whereas, the British typically use the word revision to describe the process of going over something in the vain hope that one understands the subject matter sufficiently enough to pass an exam. Americans would simply use the word study.
Tonight's wine marketing class was a review of all the topics covered over the 16 weeks that the class was in session.  I hardly remembered any of it. So pardon me, I am off to do some revision, and panic: next week will be the final examination.
