Prolly im late .. there is no difference in fact they are the same .. calyx is the outermost whorl of a flower.. it consists of sepals usually green corolla is the whorl of petals

but would you say that topics on papers in O/N and M/J 2009 most likely wouldn't come on our papers right? like paper 3 in oct/nov had nitrogen cycle (so complicated..) and genetic engineering, so we won't get those topics in paper 3 right? if they're gonna come anywhere they'll come in paper 1? just trying to use process of elimination........in whatever small way it helps lol :P

you never know
it might!

I've practiced all Bio paper 6 past papers froom 2004, and they've all basically been repetition
Other than 2009...
Last year they got some new topics, which is really freaking me out
Alright everyone, Good Luck
I'm leaving for my exam soon

To repeat what others have said, requires education, to challenge it, requires brains.
