It wasn't hard... just extremely tedious, and so strenuous on the last day that at the end of it, I slept for 11 hours straight!
Or maybe I just like sleeping. *oink!*
I've never doubted my competency in lesson delivery and presentation - even when I first started teaching - but there are some things for which the world simply wants proof in black and white. The actual worth of paper qualifications is always something I can't quite make up my mind about. A certified person is not necessarily absolutely competent, and a non-certified professional may very well be more than adequately competent.
Anyhow, I know I am competent in teaching / training, but now I also have (or will have, depending on how long shipping takes) the paper to prove it.
I should go back to bed.... *oink!*
