    Yeah, I know. I'm just saying that succession and speciation were the long answer questions in January. So its not likely they will be the long answer questions again in June.

    Also biological control came up, so I think they must've put in 3 longer questions for January. I'm not too sure what they'll put in the summer - maybe photosynthesis and respiration questions, there's so few papers to make predictions from

    Well I haven't even started revising this one yet. I got a D in the January exam and I need an A in the summer. The annoying thing is that I know the content, it's just the HSW questions that really get me. It was always going to be a bad exam!

    I've just re-sat unit 1 and I think doing past papers over and over again really helped me. So looks like that's what's in store for me over the next 3 and a bit weeks!

    Heeeey everyone!
    I did this originally in January '11 .... i ended up with an E. LMFAO. :/ I guess its not something to laugh about. But yeah Realistically i need B.... But if i manage to get a C i could deal with that. I just completely bombed the exam. It was loads of HSW and i suck at that hahaha. Totally revised the wrong stuff. Just an awful exam.
    Hoping to do 100x better this time!

    That was an awful exam, too much application and its not what I'm good at at all !! What do you think the grade boundaries will be for this out of 75? Previously its been 41/75 !?! What does everyone predict to come up ?

    Hi, I've looked through the site and cant find any threads on this exam that have really taken off, so with the exam swiftly approaching I think it would be good to have a thread that we can all use for revision and general discussion on this exam.....

    so, how are people finding the revision for it etc?? ...

    basically am stuck on genetics part. If a gene codes for a specific polypeptide chain how can you have different alleles which are the same gene because different alelles have different polypeptide chains( they usually have one amino acid thats different) and that would therefore make them different genes

    Is it that the differences are so small, i.e. one amino acid difference still makes it the same polypeptide chain?

    very confused
    any ideas or explanation would be helpful?

    Alleles are variations of the same gene.

    yes, i think that only a change in one or two amino acids won't affect the total polypeptide chain so the same protein is coded for (so same gene), but that difference is enough to change the characteristic it codes for....

    make sense?
