Of course it's possible. If you understand how the questions work, recognize what the question is really asking you (don't over-interpret), and can critically think your way through a problem, passing in two weeks or two days isn't an issue.
Some people really need a solid several weeks of studying before confidently passing. I took a 6-week review course first, and that's what *I* felt I needed. Some use a book for a week and do fine too.
The bottom line is, do you really know the material? Rote memorization doesn't work on this type of exam. You have to be able to take the knowledge and apply it correctly, in many situations. If you can do that now, you can pass
