Finding it really hard to do these essays, I'm resitting as an external student so don't have much input into how to write them. Just trying to do 'Uses of DNA in science and technology' Where do I start? also as long as its relevant does it matter what you say. The mark schemes give you a plan, do you have to include all the points for top marks because i find that I don't have time to include all the points from the mark scheme! please help
