Hey Rick,
If you are applying for sponsorship then more than likely 'yes' it will make a difference.
Yet if you are going down the self-funded route-then I think they will be more interested in how many flying hours you have and where you trained.
If you goto UNI then they will be more interested in what degree you have.
Don't worry if you get bad results as you are still very young and there are so many routes you can take.
Just out of interested, what a-levels do you have?
