Hi, Gretchen.
As a trainer myself, I would suggest you find Office training from a local training school that offers what the industry calls "apps training".
If you navigate your web browser to
http://www.microsoft.com/learning and click the link reading, "Find Training", this should bring you to a page with a link for "Classroom Training".
Microsoft Official Curriculum (MOC) is usually good materials to learn from but are only available to you when you take a MOC class from a Microsoft Certified Trainer (MCT).
After you find a course that you like, you can find a local training institution that offers that course. Note that many training centers may offer to to deliver many of the courses but won't actually deliver the courses unless enough students sign up for
the course. If signing up for a course, ask how often the course is delivered on average for a given year. Obviously, the bigger training centers will more than like deliver course more often with an experienced instructor.
Note that there are practice exams available on the market from Transcender, MeasureUp, and SelfTestSoftware (STS) but Transcender and STS are owned by the same parent company (Kaplan) and offer roughly the same exam questions at different costs. STS
merely offers less questions for less money.
Tip: Most Microsoft exams are based on the products' own help files.
Be sure that are takeing exams for the latest version of the Microsoft products, for example, Office 2010 - not Office 2007. This way, your certifications are valid for a longer period.
Good luck on your certification goals.
Best wishes,
