I have been advised from a member of staff at the flying school to get the Air Law exam passed before I start training
Great advise and at the point. And, it is a common sense approach though.
Knowledge of air law is essential to situational awareness and it is of utmost importance to have a good understanding of the ramifications before getting airborne.
It is all about maintaining the safety of flight. Don't be fooled about the idea of just passing an exam. That's definitely going to pose a huge challenge down the road as you explore the flight environment which is really complex. So study hard to gain insight and understanding, and use your instructor as a reference point to guide you. That's the way forward.
