Echoing what others have said, hard work and determination can pay off. This was my plan initially, but life managed to get in the way and, as a result, I didn't complete A-Levels. Instead, I work a soul sucking job that has just paid for me to pass my PPL, and I'm working through the modular route. Yes it's expensive, and if you can get onto one of these courses, then amazing, but do have a plan B, C and D as you may need them. My current plan is I'm doing a part time university degree, which I'm hoping will help when it comes to it, but it's a long term plan.
However, if you are that passionate about the career, you will always find a way to make it work, even if it takes you longer than you'd hoped.
Best of luck with your dreams
