I like the way everyone recommends joining the UAS as though it is something you just apply to join as a member.
There is reasonable competition for positions in the UAS, also certain minor medical conditions that may not preclude you from holding a class one can prevent you joining the UAS; so you the chances of getting one of the VR non bursar positions is far from guaranteed.
Further to this I understand the UAS have really cut back the flying syllabus in recent years. So the hours obtained form the UAS over 3 years may not be that significant.
Also to add a degree is not a back up, relevant work experience is, so unless you have 5 plus years of post graduate work experience the degree it self isn't that useful.
