There are various courses available at Graduate Certificate or Graduate Diploma level which are covered under FEE-Help, in conjunction with a University.
The majority of these take you from nothing, to CPL and MECIR or Instructor Rating.
In most cases you're required to complete an Undergraduate (Bachelor) degree in conjuncton, however if the University accepts previous study etc, then it is possible to enrol in the 'Postgraduate' Certificate or Diploma, without needing to complete another degree.
This means that instead of taking 3 to 4 years, it can be completed in 12 months.
Pretty unlikely that someone 18-21 would be accepted to a Postgraduate course without the associated Undergraduate degree.
Hope this info helps.
As for me, I've accepted the offer and will see where this all takes me. I'm not going in to it with my eyes closed,
As others have said, we only get one chance at life.
