Plausibility of 2 A levels in one year

I've known people do something similar - e.g. take A levels and then take Biology and Chemistry in a year so they could read medicine (he got A*A* and a place to read medicine).

How are you intending to do this (and what country are you in)? If you are in England and aren't going to be attending a school then the practicals for Physics and the NEA for Comp Sci are likely to be difficult to sort.

I live in England and I was intending on teaching myself most of the content as I think I'm capable of doing so and did something similar for FM. I think my current school are very supportive and would not be against allowing me to use their labs during lunchtimes or after school hours to complete required practicals. I'm not too sure what is necessary for NEA for comp sci - would I just need a teacher to grade it?

If you want to do this then I suggest you talk to the relevant staff sooner rather than later. Returning to school after A level, not on roll, raises child protection issues as you'd be an adult who'd need escorting. The supervising of the practical and the NEA - and the marking - would take a fair bit if effort by staff for which they wouldn't technically be paid, so ask politely, understanding that they'd be doing you a significant favour. If they do AQA they would have to enter you as a centre candidate for Comp Sci as it isn't open to private candidates.
