"Hi Don ... I took the Instrument Knowledge Test yesterday (Monday) in St. Louis, Passed with a 93%. The four questions I missed had nothing to do with HSI, VOR, DME Arcs, or holding pattern entries!!! THANKS FOR TEACHING A GREAT COURSE. I've encouraged my 182 partners to attend when they're ready to start their IFR training in earnest."
