I have found the best way to test your skills is practice one thing at a time. Set a weekend of camping aside just for working on firebuilding. Bring with you all you need, start with stuff you bring and slowly start taking stuff you brought and putting it away in your bag until your left with next to nothing. I like to start the trip with everything and finish using nothing more then my knife.Once you get good at one thing set up a weekend for something else. (ex: shelter building, food/water gathering, ect)
