I did an As-level in photography at night school. It was interesting in that if got me taking photos of stuff I wouldn't normallt shoot, but it's very much about the art rather than the photography. your pics have to be in focus and well composed of course, but you then need to be able to relate your pictures to those of other photographers, saying how you were inspired, or used this technique that person X made famous. not really my bag
As for using a G10, you have to do one term using film, so you;d need to pick up a film camera – you have to do your own printing of 35mm prints
