Have to say that CPL training was a breeze after IR training, although it was tough getting used to looking OUT of the window again! Anyways, IFR taught me how to fly exactly (attitude, altitude, hdg, etc.) as well as procedures. Have you done your IFR training? A CPL w/o IR is pretty useless IMHO...
Anyways, the CPL instructor is a KNOB and shows EXACTLY how INCOMPETENT he/she is. Change instructor/ATO and get on with it!!
