Congratulations.....it is a wonderful feeling to find the right path....the right goal for the future. That gives a good motivation to make it through all the schooling necessary to get there. I am surprised that you have so much schooling to do since you already have your BS & masters. I guess all the pre-requisets add up into several years.

I wish you the best....math is tough....made it through calculus for my computer science BS....so I feel for you.

Good luck,
Debbie
