I've been keeping up with these videos and watching for my revision of this exam, our class has had supply in the subject for the entirety of the 2 years and has learnt nothing. Do you know if the entire specification will be available by the time of the exam this year, as in I wont overtake the videos and have not learnt it all by the time of the exam? I really do appreciate this as a resource.
