Checkrides- how to correct for VOR/IFR mistrack?

Hello. In checkrides for IFR and above, how does one correct for a mis-track to the required VOR and/or IFR? When I try to turn to intercept and get back on track, she yells at me for not flying the correct VOR/localizer heading. Although not fatal, her displeasure adds to the displeasure basket she's building up and makes for less error later in the flight before she reaches her limit boots me out of the plane (not really!). Many many thanks for any advice. I'm going to post this also over in the school forum. I'm sorry if this is in the wrong place here.sj
