My first PFT

Well, I've got it scheduled...my first PFT. It'll happen this thursday at 4pm. I've got mixed feelings about it, as I don't feel quite up to par, yet. I know my crunches and run are where they need to be, but my pull-ups are what scare me. I've been consistantly doing about 5, but I need to double that...preferably, quadruple that. I've still got 6 weeks to work out a final PFT score of 225 or greater. My personal goal is a 250. I'll be bustin' my rear, but I will do it.
