Have produced a 40 mark Mock Exam for the G495 Advance Notice article for June 2014. It contains a range of questions on each part of the article. The mark scheme is also provided.
Please also take a look at the Matthew Arnold VLE for Physics. They produce fantastic resources each and every year that always provide me inspiration.
Another great source of information on this specific topic is the CAPT network. They always provide questions and it is a great source to voice your thoughts and ask any questions.
