Are you taking a class or a crash course before the test? I had to take the 30 hour class and took tests throughout to build up to the big test that counted for certification. The test really is not that bad. The only thing is a lot of the questions have more than one correct answer which can be tricky. Each section has about 6-10 questions on the test.
Once you pass you get a certificate and your certification is good for 5 years.
It is worth every penny and every minute invested!
The test is not difficult if you read the material thoroughly. The class is designed to translate the material into a practical, real life situations. The text included sample tests and review sections. I would recommend taking the full class as opposed to the 1 day crash course if you are taking it for the first time. Once you've passed it and come to a time where you need the recertification, the 8 hour class is a breeze.
I've found it to be invaluable in my career.
Thanks for all your replies! My class is a one day class. I had not choice do to scheduling issues.
Glad it not as hard as it seems. The most trouble I have had so far is remembering what sickness you can get from what food. But If I keep at it then I should do ok.

Mine was a one-day-deal. I was required to pick the book up a week or so before the class. If you read the book and answer the questions at the end before you go to class, you will be just fine. I did the whole book in one night (I'm a speed reader ... one year I got 10 books for Christmas ... had them all read before New Years Day).
The class/test is mostly common sense. Like I bet you already know you're not allowed to spit on the floor in the kitchen, right? 
It's a great class. Logical. Common Sense.
And my family is now no longer allowed to buy things from bake sales!
