Follow Certain Steps Toward Leed Exam Prep

I am looking to obtain professional accreditation in the green building rating system.  There are three things I have been told I need to have accomplished at least one of in order to be able to qualify to take the leed exam.  They are:  attend an education program that addresses green building principles, work in support of a LEED-registered project, or work in a sustainable field of work.  There are also various leed exam prep websites and a handbook I can research to assist in exam preparation.  I have learned there are multiple courses, as well, that can help to get me ready for this important certification.
