Hi Rhianrach. I'm used to looking at a lot of CV's having spent many years in recruitment. I'd condense it to perhaps 6 or 7 main bullet points. Put the most important duties at the top and combine some of the duties that you could consider to be of less importance. I'd remove the last 2 bullet points altogether.
It's also always a good idea to tailor your CV to the specific post that you're applying for. So if you do have the experience that the empoyer is asking for then make sure this is very clear on your CV and prominently positioned.
