Densmore immediately came to mind, since I’d taken the course last summer and it served me exceedingly well. On their website, you can download 2 simulation packages containing 7 cases in each package. The packages mirror a full UFE – 1 5-hour comprehensive case, and 6 smaller multi-competency case averaging 80 minutes in length.
The cases are free, but the answers are for sale for $60 each. The price is reasonable, as the benefit you will gain from studying these cases more than outweighs the cost.
Disclaimer: I’m not getting anything from Densmore to recommend their stuff. I’m just a satisfied customer!
I also recommended PASS, which I didn’t personally attend but a few of my friends did and they passed the UFE this year as well. I took the PASS CKE prep course in the fall of 2005, for what it’s worth, and passed that test on the first try.
Unfortunately, it doesn’t appear that they offer cases for self-study, preferring to focus entirely on their courses, which require a more significant financial outlay.
As well, you can download prior year UFEs and evaluation guides as a member of your local Institute from their website.
Good luck to all 2007 writers, and keep sending me ideas for blog posts!
