Also i heard that the training is equivalent to a degree, is this true?
This question, and whether to get a degree or not has been debated much here before, a search will prove this.
I'm at uni and I use my student loan and my part time job to pay for my hour building, I got my PPL whilst I did my A Levels. I live at home, so my living expenses are reduced over living in my own accomodation. You could do your PPL whilst at uni, but it depends on your circumstances, i.e how much money will you have left after you have paid all of your out-goings. Do some calculations and find out.
