Installing copper pipework to a radiator with worksheet at the end

A college based training/assessment normally done at the end of level 2 in Uk. It involves piping up the radiator in copper. Last video i made details the radiator installation.
At the end is the worksheet feel free to take a photo of and use has an exercise or for what ever you please. This is about doing an installation following diagram specifications. It is unusual to have pipes 100mm apart and also to have the drain valves located where they are - but we have to follow the diagram!
