I would not take it right after your course, give yourself a few weeks after you get back home to review everything. The best resource was the CWOCN certification review book. I believe I got it from Emory, I printed off a PDF form and mailed it in with the money.- I just tried to find the link online, without result, but since you are going there for your wound program, look into buying their CWOCN Certification Review book while you are there, there is also a practice test in the back of that review book if I do recall.
That Was awesome, and whatever stuff I did not know out of that book, I went through the other books to read.
There also are test questions in the back of the chapters in the texts required for your wound and ostomy classes.
Become a member of the WOCN if you are not, then you have access to the member library which has a catalog of all the old journals, which all usually contain a CE with test type questions for review. - those were really helpful.
Castle worldwide sells practice tests for 30 bucks a pop. That was so helpful and well worth the investment to see where you are at.
Review all your practice tests for certification, and expand on all the answer, why this one is right, why this one is not the answer. Especially when comparing the different types of abdominal surgeries and diversions.
Most of all, just start with the TESTING PLAN that is outlined in the application booklet when you apply for your exam. THAT IS WHAT IS ON THE TEST. Don't read about stuff thats not on the testing plan. I would recommend to go through the testing plan and then utilize all your resources to learn or relearn the info, then at the end of review of the testing plan take the practice tests. Don't start with any practice tests first because you will feel like you have no idea what they are talking about.
Best wishes, and congrats, on working toward the GOLD STANDARD for certification!
