I have been a silent lurker on this website for months but it has been such a great asset!! So, a little background is necessary.  I have decided to make a career change and focus on project management.  With my years of teaching and running my own business my application was accepted to take the PMP exam.  I began studying in January, ~two hours a night.  During the last two months, I spent about 4 hours a night, weekends included.
