For what it's worth, here are my step by step instructions for those well-versed in the english language who plan to take the Step II CS:
1. Buy the cheapest CS prep-book you can find. Better yet, borrow one.
2. Skim this book while in the car/train/cab/plane/hovercraft on the way to the test. If walking to the test, sit on a bench while reading to prevent personal injury.
3. On arrival, throw the book in the garbage, even if you borrowed it.
4. Enter the pro-metric test facility.
5. Using a zen-like mastery of your own impulses, resist the urge to punch the proctor, secretary, or other test-takers in the face as you contemplate the fact that you could have taken a nice vacation with the money you are spending on this test.
6. Using the formulaic and mindless instructions undoubtedly set forth in the prep-book (which you recall is now in the garbage), complete the test without registering a single independent or creative thought.
7. Leave the pro-metric test facility.
8. Drink heavily in a vain attempt to eradicate the experience from your memory.
This is exactly what I did, and like everyone else, I passed the damn thing.
