QUESTIONS AND COMMENTS
Do you know of any sites like Chemguide covering physics and biology?
(For useful or interesting links apart from physics and biology sites, see Chemguide's links page.)
Otherwise, there are a quite a lot of sites out there covering physics and biology at this level, but my impression of them is that they would be good for revision, but not so good if you were struggling to understand something in the first place. If you want to find what is available a Google search on "a level" physics or "a level" biology should throw up a good selection.
If you are doing some other exam - IB, for example, or Scottish Highers - you could try searching for these in a similar way, but it would still be worth looking for A level sites (and vice versa for A level students).
Physics, especially, is probably a difficult subject to explain simply on the web, because so much of it is mathematical. Calculations are very hard to do well on the web.
Personally, as soon as some maths appears in a chemistry web site, I switch off - and that's despite my having written a chemistry calculations book. There are too many distractions. It is too easy to feel that the calculations are boring, and "I'll just see if I've got any e-mails." or "I wonder if anyone else is on-line for a quick chat." - or whatever else you do with your computer to avoid doing anything useful! (In fact, as I was writing this, my mail program showed an incoming e-mail and so I broke off to see whether it was anything interesting. It wasn't. It was just flybe.com offering some cheap flights which I don't need at the moment - but I read it anyway!)
If you are trying to learn to do calculations, you definitely need a distraction-free environment. They need too much concentration.
If you do come across a good physics or biology site which helped you to understand physics or biology topics rather than just revising them, please let me know via the address at the bottom of the about this site page, and I will add some links here on this page.
