God not this... from what I can see, there was nothing wrong with the paper from what my triple group classmates have provided. I did Unit 1 last year and honestly, I think that there wasn't anything wrong with the questions they asked.
What is an independent company? Well what does independent mean? What is a company? A company which is free to conduct what experiments they want. Even if that is wrong, it's one mark down and not 6. I don't see how people say there was no biology when really there were only 3 marks on drug testing.
