    on the first question, was it only cell wall, starch and chloroplasts? i wrote chloroplasts and that eye thingy mabob...

    personally I found this exam much harder than the psat papers. In the past papers I was getting good As but im not sure I will in this one,. There were lots of tricky 1/2 marker HSW questions that will cost me. I thought the structure of this exam was much different to previous years. Normally its knowledge adn then the last 2/3 questions gives a scenario plus some graphs and HSW works questions but this year it was spread through the whle paper. I thought half the spec wasnt even examined! I would have doen equally well (or badly) if i hadnt turned up to a single bio lesson. Too much HSW not enough knowledge questions !!! HSW has cost me an A
    I like the whole HSW and applicatiom of new ideas.The application of HSW seperates the people who have just revised alot but who aren't actually that bright from the people who are genuinely quite clever. I'm sure with enough effort anyone could learn how to quote a whole tect back, not everyone has the ability to do the harder stuff in applying knowledge, which at the end of the day universities and prospective employers are looking for.

    HSW isnt an accurate indicator of intelligence. I got 10 A*s wwhilst doing little revision i dont need some HSW to tell me im intelligent. The subject is biology otherwose universities should just do IQ tests.

    plus I dont mind a few HSw questions like in past papaers but I felt this paper over did it I thought it was excessive

    sorry if ive missed it, looked thru most of the posts... but
    what did people write for how diff base sequence for protein may lead to a diff in structure?

    FFS. But it's a Biology A level... not a HSW A level.

    :elmo: I agree m8 but sometimes examiners should just think about the student and that it's not fair to test them so harshly with so many HSW questions when they have been told to learn a whole text book for their AS level and should cut them some slack and all that. At the end of the day student x may know all the biology in the world but won't get the grade they deserve because they couldn't apply it right to some stupid question, where as the student y who has merely drifted through the syllabus has practised a few HSW questions and to their luck the whole paper is full of them. Hardly fair. This paper had so much of this, and I learnt so much biology for a paper which prolly contained about 20% of unit 2.

    HSW is Biology. You have to look at data and apply your own knowledge to this data. Kowing text book definitions of Genetic diversity and Species is no good on its own. You have to be able to apply this knowledge to unfamiliar situations. The way you sound like you want the exam to be done is everyone who revises should get an A. If you are good at Biology then it shows on the HSW questions.

    And for the similar shape i wrote about competitive inhibitors, etc..
    Urgh i'm frustratedd =( I think i effed up the whole leaf question.
    was competitive inhibition wrong? cos i did that too...

    Not really, as the nature of HSW contradicts the nature of a markscheme'd examination, in that there are hundreds of ways they can be answered, but only one way AQA want you to answer.

    No you dont understand what im saying. I dont mind some HSw questions about interpretating graphs. The way I remember it only one or two of the questions was onterpretating graohs.

    let me make it simpler - HSW is okay but I thought it was overdone in this exam. It should be more like previous years. Why the hell did the exam board tell to learn all tht stuff in the spec i just wasted my time i could have spent tht time doing more useful things. I could have gone to no biology lessons and done equally well. Are you saying it takes no intelligence in answering questions other than HSW ones

    I can see where you are coming from but how can the gifted people stand out if all the a-level required was learning a text book off by heart. If that was the case I think it would de-value the who a-level. One of the reasons Maths is a respected A-level is because each question is unique, you can't just learn textbook definitions, you actually have to show you have the ability to apply your knowledge to a wide range of questions.

    If student X did know all the Biology in the world then they would've drifted through those questions. The impression I got when I spoke to people after the exam is the ones I know to be of higher abilities seemed to be getting the rights answers, the lower ability ones generally struggled to apply what they knew to those situations.

    You're not wrong, it was a competitive inhibitor. Not sure that stating that will be worth anything ont he mark scheme though.

    So you could've gone to no biology lessons and you still would've known about DNA being in triplets and that introns are non-coding parts of the base sequence? Don't be ridiculous! I'm not saying it takes no intelligence, obviously it takes an intelligence of some level. However I'd say that most people that get accepted onto Biology A-level courses could get an A if there was no HSW and they learnt the text-book off by heart.

    I would agree with that point though. You can counter that by writing every possible point that might be on the mark scheme.

    Not rly, Biology back in the day according to my teachers was basically all knowledge, none of this HSW 'crap'. The A level was harder and people can argue that it has been getting easier. It's the HSW that unfairly trick candidates and they lose marks.

    This paper did not contain enough biology from unit 2, like I said prolly around 20% maybe a bit more but how can this be fair and a better way to assess someone's biology knowledge because at the end of the day that's waht exams are. There's nothing wrong with papers with a few HSW but when it fills a paper that is so weighted like this unit I would hardly call this fair.

    What's done it done, however. I know I will lose so many marks for not 'applying' it correctly and I will be deemed the 'worse' candidate even thought I might have known the content from the text book inside out.

    what i am saying is the amount of HSW questions were excessive. cant you agree with me that there were more HSW questions in this exam paper than previous yeas?

    Im all for HSW questions but within limits like previous years. HSW is what the EMPA is for which I found was quite easy actually.

    your saying its people of higher intelligence should get As rather than people with less intelligence. when youve got a job your gonna employ someone with the required knowledge not just someone wiht high IQ. for brain surgery would you rather have the guy who has the knowledge and worked hard for his degree. or some guy with really high intelligence. Knowledge is importnat. you build on it at uni so youve got to know the basic stuff at As so they shuold examine it and see if its there. I think a Uni would rather have someone who undertands how genetics works rather than someone who can answer why using 10 leaves is beneficial (I put reduce percentage error is that right :P)

    I think the light sensitive eye may be a neutral, it's quite a strange thing.

    The only place I can think of the light sensitive eye exiting in humans is ine the eye itself. If humans don't contain that eye thing then surely you will get a mark. Can't see it being classed as neutral though, it's either right or wrong.

    I wouldn't class HSW as 'crap'. It obviously differentiates between candidates who simply learn the book off by heart and those who can adapt the knowledge they have learned into given situations.
