Hey guys
I don't know if this will be particularly helpful but revise the 'ideas about science' part of the revision guides if you do not do so already!
I've noticed the answers to the questions about correlation/cause and risks are explained in this section and I only noticed quite recently lol

Haha, its not too difficult to say the issues with it though (that's what I'm hoping for). At the moment, I'm not too stressed. I've thoroughly revised just hoping there are no curveball questions in there (or that I go blank!). What about you?

I know this is a stupid question but what do u mean by issues? Like termination, abortion, false negatives? stuff like that? Because I'm love with those things, they're a god send :angel:

happy that you're calm. I'm not at all, my blood stream right now is probably 100% caffeine. loool. There's going to be at least one, they always trick us.

Yes exactly!! You shouldn't be too stressed, the grade boundaries are very low so I presume the amount of revision you have done will be sufficient. Good luck :h:

Oh right, awesome (; good point about grade boundaries, i need to chill. Thank you, you too. My dad let me take the school day off to revise it thoroughly so I should be ok. Best of luck to you x
