Hi Kerry and Gareth, to clarify the tutors at my college do teach me these things, however I am required on this project to undertake research of my own outside of what I learn there, and indeed was directed this way (as one of many sources I will be looking at) by one of my tutors. Today has been the first opportunity I've had since posting to properly sit down and read through responses. Thank you Paul for your time and detailed response, and Claire too, I have looked to and found lots of friendly advice on such facebook groups and appreciate the time.
