I learnt on my second solo nav at PPL level not to be intimidated by the 'big boys'. When doing my pre-takeoff checks and noticing an A320 taxiing behind me I failed to allign my DG. Luckily soon after I intercepted my outbound track I did a 'sanity check' to make sure I was heading in the right direction. When things were not looking like they were supposed to be below a quick check of the panel revealed my DG to be out by ~30 degrees
