I became unaware of my position on the first of my two QXCs. I made the mistake of concentrating too much on trying to correlate landmarks with what was on the chart and not watching my heading. Ended up drifting off track and becoming disorientated. Such a horrible feeling. Kept my cool and back tracked to my last waypoint. Then continued and eventually got to my destination somewhat later than planned. I learned from my mistakes and did the second QXC the next day with no problems and then passed my GST two weeks later. Happy days! I learned a lot from that experience.
