list of abv's. it'll be pretty much bang on that bar 0.1% or so because it's a pre determined attenuation of the yeast and amount of sugar...

Simple answer to your question is no. I could brew 5 ales all with different OG from 1.060 to 1.030 I could get all 5 finish on the same gravity. There is no way of working it out unless you have a Refractometer as well.
Somebody that may well of brewed the same kit could give you a rough idea of it's final ABV
