My film age category

The age category my film is aimed at is a 15 I chose this age category because the film is going to have the following contexts which will be irrelevant to kids at young age because my film is going to be a gangster biopic film production. It is aimed at youthful teenagers who watch this type of genres many may see this in modern day life and understand the context. So this filmed will be aimed at them as they will understand the film relevance and whereas kids may not have experienced this is modern day life and will not understand the context so I had chose this film classification as it is most relevant.
