Has anyone taken the Wonderlic test?

As part of their entrance testing for their nursing program, Concorde College in Aurora uses the NET and the Wonderlic. Has anyone taken the Wonderlic? I have downloaded the SAMPLE 15 question, four minute test, but Concorde says that theirs is a 12 minute test. So how many questions would that encompass I wonder? As it is, I panic on timed tests, so any help or advice would be greatly appreciated. Thank you.
