I am fine with Unit 1, i am perfect on Topic 2, but the Cystic Fibrosis thing catches me out a lot! And on Topic 1, i get confused easily on the blood clotting process. The books diagram makes no sense at all.

Which book are you working from? mine were equally unhelpful, I spent ages trying to figure out blood clotting, ended up just watching every youtube video I could find on the topic and I think I've kind of got it now.

I think I'm fine with unit 1 apart from the core practical about enzyme concentration :/

I do AQA and to be honest it's a lot easier ... But with a lot of revision you can do great

If suggest using www.cram.com for flash cards you can get a variety and they are great to use to refresh your knowledge

I keep getting high Bs in my Biology mock exams but I know I can get an A!!! I Just hope I can go over Unit 1 in the next two days - I've gone over this throughout the year so I know I'll be fine but I pray there's no questions that catch me out - there always is :'(

My weak point seems to be the apolipoproteins! really hoping we don't get a question on them, and my revision guide doesn't even seem to cover them, although my textbook does,
Also need to go over cystic fibrosis treatments. :/

I have realized that most questions are mostly based on practicals and the actual knowledge is actually incorporated in the questions e.g. why do you have wash the beetroot when cut and you have to day to wash off excess dye after cutting the beetroot and damaging the membrane , releasing dye
