Video for the actual internal
PLEASE watch these sets of videos whilst doing the internal, if you follow them step by step at the same time as working, there is no reason why you will not achieve Excellence.
As this internal is a report based internal, you are actually allowed to watch this video whilst doing the actual internal. Admittedly the videos are longer than the lesson so you will need to do this at home, do not try and do this all in school.
