    The main problem I have with the exam is that it seems so straight forward when in reality it's not.

    Some people are fortunate enough to have the same mind frame as the people who write up the mark scheme.
    I am sadly not one of those people but hey, might as well give it everything you have
    This is so me
    I think of the stupidest answers
    Reading the how science works esqe paragraphs and stretch and challenge questions in the textbook helps though. Also try to draw links between parts of the course (eg in F215 the brain and control of muscles to F214's homeostasis and control)

    This is AS...? Won't be able to answer as well as someone doing it right now soz

    Structural/Fibruous protein
    insoluble in water
    Made up of amino acid monomers
    3 polypeptide chains with crosslinks between
    also H-bonds between polypeptide chains
    Every three amino acids there's a molecule of glycine or something like that
    Hydrophobic out, philic in
    Where it's found in the body lol

    Could someone clarify what the texbook means on page 60, LHS of How the structure of chloroplasts enables them to carry out their function? I'm confused about the relationship between lamellae, grana and thylakoids.

    The first bit says:

    "The inner [chloroplast membrane]... is folded into lamellae (thin plates)..... each stack of lamelleae is called a granum (plural grana"

    But further down it says that grana are not stacks of lamellae, but actually:

    "Grana are stacks of flattened membrane componenets called the thylakoids".

    The diagrams do not ever label lamellae, only ever intergranal lamellea, so what is the answer to this (apparent) contradiction? Is the textbook wrong, or is it right but just poorly worded? Could someone explain please! Thanks!

    Thylakoids: disk thingies.
    Granum: Stack of disk thingies.
    Grana: plural, stacks of disk thingies.
    Lamella: the membrane which you find the stacks of disk thingies on

    Not even trying to be patronising, this is literally how I remember things. Move outwards.

    Nope, sorry! You could try teachers at your school or a tutoring agency, they could hook you up with one

    Does anyone have any good revision techniques? Or like how to do good in the exams?

    I know this sounds really broad and not specific at all, but I just find it really hard to do good in the exams. I generally know the content but my answers always seem to be lacking or I just don't understand what the questions are asking me.

    I know I need to practise exam techniques, but how do I actually do that? One person suggested I go through papers with my notes, the mark scheme and also the examiners report.
    I will definitely be trying this out but does anyone have any other ideas? Or have any techniques that worked well for them?

    I would really appreciate all the help!

    I need to go from an E at AS to a B overall to this and I'm so so stressed. The mark schemes are so frustrating - I always end up going into detail and then not actually getting any marks because the examiners put a really simple answer.

    How is it even possible to get such high marks in the coursework?

    That for someone who is aiming for an A* oh god haha, probably gunna have to get practically full ums in the exams like last year fgs
    I've got no idea how they get those marks.

    I've got 33 for physics and probably similar for chemistry. That means that I'll need roughly 95% UMS in the exams for both subjects.

    In biology the practical assessments seem more difficult and I do worse than the other subjects, so there's no chance of me getting an A*.

    Did you just miss the part where I said I've only done half of unit five lolololol, like properly learning it
    I'm a slow learner so I have to start earlier, currently on a slump and work experience, so I haven't really been working for the last few days
    And I need an A*

    I did the same thing for some reason, even though that little green book was my saving grace last year, proof I didn't look at how hard unit 5 was early in the year. Should have listened better when we were learning before mocks :/

    It's actually a joke
    Why couldn't they have put something easier (dont pelt me if you dont find it easy but me and human biology just work ok) like Excretion in unit 5 and one of the bigger annoying ones like Biotech in unit 4
    Now I think about it excretion is actually so random
