Always make sure you know exactly where the examiner/instructor wants you to divert to by pointing it out on the map if necessary.
If you didn't know where Kinross was, how did you do the calculation? On any diversion draw a line from where you are, to where you are going, measure the track accurately, in this case 120 degrees. Apply your max drift to give you a Heading and off you go. A heading by the way is really a wind corrected track.
If it doesn't look right, do a gross error correction and change the heading. This is where the line comes in. look for features that will confirm your position relative to the line. Try to find a mid point fix, time travelled then equals time remaining for an accurate eta.
