I am going tomorrow morning to sit for my national mastectomy fitter certification test. Needless to say, I am a wee bit nervous. I have been reading my training materials front and back for the last couple weeks and have over a years experience under my belt as well as a fitter's training course from the leading professionals. But I am still nervous. My company paid $200 for this test. I am worried I will let them down. I have always tested well, but I can't remember the last time I took a test, let alone a BOC test. This is the same company that certifies athletic trainers...I know how rough they can be.
I am just going to get up early, drink a couple cups of coffee, read through my literature again, dress casually and take my time with the test...it's all I can do.
I haven't been this nervous since my senior thesis presentation to the English Lit. department...ug.
