BEng in Civil Engineering, also working as a PM, dan saff... Left engineering many years ago, as it was too much like hard work! Moved over to client-side as PM as much more civilised!
Currently managing an Academy, 3 Health Centres, a new private school, and hopefully about to be awarded a new hospital... As you can see public sector is where I usually work.
With reference to Prince software 'Arthurfuxsake'. This is only really any use if you're going to be engaged on government type work. Otherwise, not worth having. Better to go for APMP certification, which is more widely accepted IMO...
