Do a smell test on the numbers yourself.  

Same procedure for boiler/heating system but perform a separate test on this.Usually the elbows in runs near the exterior walls break first which actually reliefs other parts of system.I have seen freeze ups where it was only minor a few elbows here and there.It really needs to be done on a case by case basis but it seems like your preparedfor the worst but I don't think it will be that bad. 

Buy the pump, get a 55 gallon plastic drum, cut it in half, drill a bunch of holes in it (big holes), dig a big hole in the ground in the crawl space about 6 inches deeper than the half barrel, pour 6 inches of gravel in the bottom, put the barrel in, pour gravel around the sides, set a solid concrete block in the bottom, set the pump on top of it, run your hose downhill of the house, plug in the pump and test it out (use a hose to fill the barrel).

The book contains a chapter test for each chapter as well as a practice exam.

@Russell Brazil Personally I find the 1% test generally does not work very well anywhere by my standards. 

I am in Philly as well, so feel free to reach out, it's definitely helpful to pick the brain of someone who's gone through the test for tips.

I recently passed my IL Broker's test and I'm ready to find a Sponsoring Broker to hang my license.  

I talked to my carpenters who helped rehab and they said they could put up a garage for a lot less but I know the problem is I have to do the planning, get a permit,  get the concrete guy, the electrician, ect, but wait-that's what I do when I do a rehab so I took a class on general contracting, took the post class test and scored 96% and take the exam for my General Contracting license next week. 

And true test of anyone making money in REI will tell you... it's the cost of the business we love.
