^ Same here. In one past paper we went through in class, my friend and I had both used the word 'poisonous' but the mark scheme wanted 'toxic' for the mark. I just just get it sometimes!
I don't feel like I'm very well prepared for this exam because other subjects are more of a priority for me, but I didn't understand unit 5 stuff at all and was certain I'd have to do a resit, but got an A... and I don't even know how because I was always the one in lessons who was pretending to know what they were doing but didn't have a clue! Must have been a stroke of luck there! But I did resits for AS and got those units up so I think I only need a B in unit 6 to get an A overall... but as i said i don't feel very well prepared yet so who knows?
Good luck everyone anyway!
