What to do at university?
Get drunk and sleep with lots of young women.
but at the same time have a decent paid job so that i am not frustrated by the lack of opportunities
Graduate jobs nearly always offer dreadfully low pay. Considering you spent a minimum of 5 years study and at least £30,000 qualifying for and getting a degree, your less than £20,000 (on average) salary will be a poor return.
The idea behind the graduate job is that after several years you will be useful to the company (because you are a complete spare part at first) and start to searn better money as your career develops.
Since you want to start flight training straight away, this would be a financial cock up to say the least. In short, getting a degree, the associated debt and graduate job in order to fund your flying is a ****e idea.
On a positive note, you will have a career to fall back on should the flying not work out. But remember, you certainly do NOT need a degree to have a good career, despite what your careers advisor told you.
What are the license need btw... PPL, CPL and ATPL?
This is basic stuff and you really should have read up on this before planning your next 7 years of life and earmarking over £100,000.
You will need a CPL with MEIR and an MCC these days. Make provisions for a TR course too.
Enjoy your youth. Although it is wasted on the young!
