Augmented reality is just one new expression covered in detail on Kerry Maxwell's Buzzwords page on the MacMillan Dictionaries site. It's a really excellent resource for Language Change at A level and has a very handy subject index which can show you the fields from where many of the new words have been derived: technology, business, health and leisure being particularly big areas of lexical innovation.
The Buzzwords archive is also very handy for looking at new words and phrases over the last few months, so have a look here for more. And remember, your examiners are human (at least for the time being) and like to see new examples of word formation rather than the same 10 examples from your text books and revision guides (apart from the brilliant examples in the fantastic Nelson Thornes book - ahem).
Kerry's powerpoint on new words, from her presentation to teachers at SFX in June 2008 is still available here if you're looking for some good revision material.
