if your goal is to pass the 117-202 exam then yes. recording is definitely a big part of it. there was a fundraising contest – whoever raised the most money during the week of march 12-16 won a free $100 pair of shoes from a local running store. it really was the icing on the cake! i haven't been lucky enough to find these for years. my biggest idea (which all my nightingale verse spins around). if you get into something that could potentially land you in trouble, that controller gets you out of the situation before it can hurt your image.
