ECE Exams

[MagicATC]

Don't let the 4 month thing scare you. That is what Excelsior recommends. I have only taken four and they didn't seem too bad. I feel they are a little more difficult only because they are much longer(160 questions!). There were usually really easy questions and really hard questions. They use the IRT theory to grade them(just search other posts to find what that is).
As for study time, I would keep the same habits as CLEP. It all depends on which ECE test you are gonna take. I studied 1 week for Adult & Aging and 2 weeks with Ethics and Organizational Behavior. No study for Gerontology(I used the A&A overlap before the new flashcards)
I got a B on A&A and C Gerontology. Still waiting for the other two(paper based). I had the same feeling during the test of all the other tests. You know, the feeling like I don't know anything on this!
My opinion is that ECE wants you to pass and makes it easy for a "C" so you will keep paying more money for the tests. Just my opinion though. Also get the practice tests if available.
