Has anyone ever done a level computer science privately?

I just finished y12 doing maths, cs and business however im thinking about leaving college and entering as a private candidate for maths further maths and cs instead for a number of reasons. (I no longer want to go to college and i dont want to do business anymore but they wont allow me to switch, i also prefer learning at home) But i heard a level cs cant be done privately im guessing because of the coursework? Has anyone ever done it?

It's open for private candidate but its extremely difficult to find exam centre willing to enter for you because of the coursework as they need to authenticate it apparently

Are colleges able to do this? I would like to do aqa cs btw but i read on their page, they dont accept private candidates so i assumed its impossible but is it slightly possible for my college to take me in as a private candidate if i asked? To enter me and assess my coursework since i already did first year there or is this unlikely? I would obviously pay.
