    Wow, I honestly don't know how I've done on this exam. I got confused by the question about the triplet codes at the beginning of the paper, as I didn't think that AUG would have counted since it's a start signal. But no, I was wrong ;( Also, the last questions at the end of the paper about Malaria threw me off as well, especially since I was coming very close to running out of time.

    I have never ever seen a bio exam question this lengthy - the Sickle cell anaemia question on Africans

    How about question on dietary advice? Anyone?
    I think i said:
    - eat more beef
    - less corn oil
    - substitute olive oil with butter

    then said for each one because they are high in saturated fats etc...

    Does this sound like 3 marks worth?

    I didn't go into specifics about the types because it was dietary advice and nobody mentions specific aminio acids or lipids when talking diets

    What did you put?

    Idk if you're joking but this is the opposite of what they were looking for. Saturated fats are the bad ones and they have no double carbon bonds, meaning beef and butter should both be cut out of the diet and more corn oil should be consumed. It sounds like you got it mixed up :/

    Fairly sure I knew at the time, just couldn't remember as I was typing it

    At this point I've got rid of half the content from my mind haha.

    That's what I put. I put something like eat more corn oil and olive oil. Higher proportion of unsaturated to saturated (HDL:LDL) and because they contain unsaturated fatty acids which have C=C double bonds. I also put corn oil lowers cholesterol and olive oil doesn't have an effect. However, I didn't put about consequence of cholesterol. Do you think it was required there or was it just about spotting unsaturated fatty acids in food by looking at number of double bonds?

    I think it's you put the right recomendations and at why them it could get 3. It probably had 5 marking points and the effect was 2 of them

    Yeah 3 marks for the question but possible 5 points in mark scheme to get the 3 marks

    No, mark scheme gives a lot of points but it's because different students might write different things. You only need 3/5 to get 3 marks. Every point worth a mark. That's what my biology teacher told me

    High solute conc. /low water conc inside cells, and as distilled water has no molecules in it, it would move via osmosis into the cells, and the osmotic effect would make them swell and in some cases burst.

    I'm also doing fast track biology as an external candidate - it's stressful! I found the paper hard and much harder than the past papers I'd been practising with. I completely messed up question 8 about the malaria and anaemia as I was rushing and didn't read the question properly. Need to do better on the next 3! :-/

    I need a B and definitely didn't get a B in that one! I was hoping they'd ask about the heart in detail, or protein synthesis but no! Let's hope the next one is easier! Fingers crossed for you too!

    Aw hey! Nice to hear from someone else in the same boat I think I was the only external candidate in my centre today haha. Yeah I feel exactly the same, are you taking the course to get into university if you don't mind me asking? I have a conditional offer and need a B in Biology so stressful and hard to trust myself that I'm learning the right thing as its mostly self taught! Yeah same I wish we could know our coursework sooner. Will we only know about coursework on results day? Best of Luck
    Yes I need a C in biology to get into university this September. I've tried to get my tutor to give me an idea of my coursework mark and only got "you've done very well and addressed all the feedback." So I'm hoping for a B at the very least from coursework. The marks will come out with the exam results.

    How are you feeling about the unit 2 exam?

    Ah that's good! Well done I wish mine would give me an idea of my grade! It's so stressful isn't it. I feel not too bad but it's more the unit 4 and 5! At the risk of asking a stupid question, I don't really understand the purpose of the pre release article? Should I be learning it and understanding it will I be asked questions about it in the exam? It hasn't really been explained to me that well by my distance course - can anyone shed some light ?! Sorry

    I'm the same - I don't really know what I'm meant to be doing with the pre release article so would be great if someone could help!
