How can a 17 year-old Brit make some money in this economy?

I am 17, about to finish Secondary School (I am in year 12 and a few weeks from finishing) with 7 GCSEs at mostly D and E with the single B. I got 4 GCSEs at BTEC all As and another A GCSE in BTEC from the courses I am doing. I am going to College in the Autumn and, at the end, be getting a BTEC worth 2 A-Levels from a 1 year course, after that year I will be returning to College for a 2 year course which will get me another BTEC worth 3 A-Levels. I then plan on going to Uni for x years and getting a degree. All qualifications after Year 11 will be in IT. But for now how could I make money?
