Chances of 'Models of the Atom' coming up in OCR B A-Level exam?

What are the chances of different models of atoms coming up in the OCR B A-Level Chemistry (Salters) exams? In the specification it says:

"how knowledge of the structure of the atom developed in terms of a succession of gradually more sophisticated models – interpretation of these and other examples of such developing models"

Would it be worth just making notes based on what is in the revision guide a few days before the exam? I know it wouldn't hurt making notes etc. but I'm just wondering what people think about the likelihood of atomic models coming up in an exam is like?

Just when a teacher tells you something hasn't come up in a long time, and is unlikely to, it shows up. 5 marks I'll never get back. It wasn't Chemistry, rather Physics but the same principles apply. Revise everything on the spec, because there's always a chance it will come up. You're unlikely to get a big question on the different atomic structures as it's purely knowledge and less likely to be spun into a question you have to interpret. But you never truly know :smile:
