Get flightsim 2004 or 2006 and load a baron. It's the same exact plane. Practice shooting the ILS into INDY(32 or 36 I think it is). I beat that thing like it owed me money all thanks to flightsim! I was hired in March and I had to do all the tests and the sim. I studied the cheat sheet and it made no difference. I read the IFR oral guide on my way up there to brush up on everything and aced the tests and had a coffee break while everyone was still in there taking it. Had I not randomly found my IFR oral guide while unpacking a box I probably would have spent the whole time in there on those tests. Half the things they asked left me sitting there wondering who really cares. I mean when's the last time ATC asked you to do a DFsteer?
I'd stay away from that gouge. Almost nothing in it was in my tests. Just hit the IFR oral guide/ATP oral guide and you'll ace them.
