Well, as I indicated in my response to your previous post, unless your daughter has been specifically told to buy a 'pocket' or 'compact' digital camera, I don't think that any of the cameras you mention are particularly appropriate to an A-level photography course. (I've taught photography to students but only on a recreational, rather than academic, basis). I still stick with my original recommendation of the S5700. (It's got a better optical zoom than any of the models you suggest and allows for better manual, or semi-manual, control of the aperture and shutter speeds. It's also no dearer than the cameras you suggest):

The three cameras you refer to are all so similar in their specifications that, if it really has to be one of those models, I'd simply recommend following Jno's advice and buying the cheapest.
