you will get the test results immediately after clicking finish (or exit) as well as on a printout.
However, it will take some time (several weeks) until you get your Certificate from VMware once you passed the test.
Just a quick update,
I took the exam this morning and pleased to say I passed.
I thought I should add this edit and say thanks to those who helped me out a lot, without even knowing about it.
Scott Lowe, Great book although the pages are falling out now
Simon Long, Blog site is great for a lot of useful pointers in one place, and the effort that went into the mock tests.
Mike Laverick, Many hours spent watching the training video's posted on his site.
Duncan @ Yellow bricks cool articles on HA and DRS made it a bit easier to understand for me.
I could go on and on but I am starting to sound like Gwineth Paltrow doing an oscar acceptance speach.
