Do many people take on second jobs to help supplement the 10k?
Don't be fooled it is very hard on 10K and I know one person who got a second job because he couldn't make ends meet but he is now waiting for a training review - draw your own conlusions.
If you do aerodrome or approach, you will be in and out in 6 months (as long as you pass everything.)
If you do area, you will be out in 9 months (as long as you pass everything)
It is important to emphises the IF you pass everything, it is a minority of people who go straight through without a recourse, I would recommened that you do any of your financial planning based on 12-15 months (area)
If you are over 25 you qualify for Working tax Credits and Housing benefits - be sure to look it all up.
