I am 14, living in the UK, home-schooled and spend the majority of my time online researching on my own without any sort of structure or curriculum (I research whatever may spark my interest at the time). It isn't going poorly, and my knowledge of various subjects is increasing quite greatly, but I doubt that my knowledge of Computer Science is varied enough to complete a Computer Science iGCSE.
Can anybody recommend me some up-to-date books that can assist me in learning?
Thanks.
