    I'm doing less study now than I've ever done throughout out the year, I just can't motivate myself to study...

    Possible Reason: Over 1100 posts in a month and a half ;)

    Two of those questions are samples. The question from 1971 were before the time of bell-curve marking and wall to wall gutter journalism that we have now.
    Grades weren't as segregated as they are now and nowhere near the amount of people sitting the LC than there is now.

    If a question like that came up now, there would be uproar up and down the country, Joe Duffy would receive 10000 phonecalls, this website would explode,there would be young wans and young fellas crying outside their schools on the front page of the Irish Times, and it would be a PR disaster for the SEC. Remember the Leaving Cert is an internationally recognised qualification and prides itself on it's fairness and ability to discriminate between candidates of different abilities. It's reputation has already been diminished with the project maths course, especially amongst engineering bodies.

    Btw, the importance of MacDuff could easily come up. He's a pretty important guy.
    please nooooooooooooooooooooooooooooooooooooooooo

    For GVAV, do you have to talk about characters when not specifically asked? the question in my mock was
    'The general vision and viewpoint of a text can be changed or reinforced by the ending of the text'

    Nothing on characters or relationships, so I just discussed everything in general, talking of characters only where relevant. But according to my teacher, that is the reason I didn't get full marks, as apparently I have to bring in my characters more explicitly..

    I got 68/70 for that: I discussed all the usual subsections and how they created a GVV in the texts, and then discussed the ending and whether it changed or reinforced the GVV :P

    just looking at that question page someeone posted.....

    1971: Discuss the view that Lady Macbeth has more in common with the Witches than with Lady Macduff.


    The minor characters are “sketched lightly, and are seldom developed further than the strict purposes of the action required” (A.C. Bradley). Discuss the characters of Malcolm and Macduff in the light of this statement.

    Discuss the importance of Macduff in the play.


    :eek::eek::eek::eek::eek::eek::eek::eek::eek:

    Is it bad that I dont think the Lady Macbeth q is that bad...? :o
    She has more in common with the witches because of her evil side and involvement with evil spirits, and her ability to manipulate and influence macbeth, just like the witches
    However she also has things in common with Lady Macduff because both were abandoned by their husbands and die in the end :pac:

    No offense but im getting sick you of you asking this, you asked it soo many times. Youre looking for people to guve you reassurance. What if i said no? Would you just stop studying?
    Put the head down, get on with it and see how you do

    Going up 50 points isn't even hard when you've got 250 points in the pre... :confused:

    Do you feel you overperformed in the pres Badwulf?

    I approached it in a similar way and got 59/70.. Did you talk about the characters a lot? I honestly don't know what he means by talking about them more, I do refer to characters where relevant and how they help create the vision, how you sympathize with them etc. If I went into any more depth I would end up with like 8 pages :pac:

    It's as easy to go from a D1 to a C1 than to go from a B1 to an A2 imo. Unless you've a learning disability or something, then I completely understand the difficulties you'd have going from 250 to 300 with 9 hours study.


  • Registered Users Posts: 411 ✭✭Badwulf


    Suppose your right, I do ask that question way too much, tbh that question prbably makes up about half my posts :P

    Today's study was shocking. So unproductive. Must get a lot of English and Geography and Maths done tomorrow..

    I'm getting up around half 10 in the morning these days so I can stay up and study for an hour late at night. I don't know why but I find it so much easier to study when it's night time.

    Best of luck to everyone anyways :D

    Endotherms : Generate their own heat from metabolic reactions.
    Active transport : Energy is used to move molecules against a concentration gradient. Eg – low conc
    to high concentrations

    The Nervous System
    Neuron : A nerve cell
    Threshold : The minimum stimulus needed to cause an impulse to be carried.
    The ‘All or nothing Law’ : States that if the threshold is reached an impulse is carried, but if the
    threshold is not reached no impulse is carried.
    Refractory period : Short timespan after a a neuron has carried an impulse during which a stimulus
    fails to cause a response.
    Synapse : A region where 2 neurons come into close contact.
    Synaptic cleft : The tiny gap between the 2 neurons at a synapse.
    Reflex action : An automatic,involuntary, unthinking response to a stimulus.

    Endocrine System/Skeleton
    Exocrine glands : Release their product into ducts/tubes.
    Endocrine glands : A ductless gland that produces hormones which are released directly into the
    bloodstream.
    Hormone : A chemical messenger produced by an endocrine gland and carried by the bloodstream to
    another part of the body where it has a specific effect.
    Ligaments : Strong, fibrous,slightly elastic tissues that connect bone to bone.
    Tendons : Strong,flexible,inelastic fibres that connect muscle to bone.
    An antagonistic pair : 2 muscles that have opposite effects to each other.

    The Human Defence System
    Pathogen : An organism that causes disease.
    Immunity : The ability to resist infection.
    The general defence system : Acts against all potential pathogens attempting to gain entry to the
    human body and is divided into 2 lines of defence.
    The specific defence system : Attacks particular pathogens.
    Antigen : A foreign molecule that stimulates the production of antibodies.
    Anitbody : A protein produced by white blood cells (lymphocytes) in response to an antigen.
    Induced immunity : The ability to resist disease caused by specific pathogens.
    Active immunity : The person produces antibodies in response to invading antigens. This gives long
    lasting production.
    Natural active immunity : When a pathogen enters the body in the normal way.
    Artificial active immunity : When a pathogen is medically introduced into the body.
    Vaccine : Injected or taken orally into the body, is a small quanitity of a microbe that is dead or is
    treated in some way to reduce its effect. The vaccine stimulates the production of the corresponding
    antibody, giving resistance to the microbe, eg – polio, whooping cough.
    Passive immunity : Antibodies produced in another individual are given to the person.
    Natural passive immunity : Antibodies pass from mother to child across the placenta and in the milk.
    Artificial passive immunity : Antibodies produced in another animal/human are given, eg –
    antitetanus injection.

    Human Reproduction
    Gamete : A haploid cell.
    Gonad : An organ that produces sex cells in animals.
    Ejaculation : The release of semen from the penis.
    Secondary sexual characteristics : Are features that distinguish males from female apart from the
    sex organs.
    Infertility : The inability to produce young.
    Ovulation : The release of an egg from the ovary.
    The menstrual cycle : Series of events that occurs every 28 days on average in the female if
    fertilisation has not taken place.
    Insemination : The release of semen into the vagina, outside the cervix.
    Fertilisation : Occurs when the nucleus of the sperm fuses with the nucleus of the egg, forming a
    diploid zygote.
    Birth control : Involves methods to limit the number of children born.
    Abortion : Termination of pregnancy.
    Contraception : The deliberate prevention of fertilisation/pregnancy.
    Implantation : The embedding of the fertilised egg into the lining of the uterus.
    In vitro fertilisation (IVF) – Involves removing eggs from an ovary and fertilising them outside the
    body.
    Morula : A solid ball of cells formed from a zygote by mitosis.
    Blastocyst : A hollow ball of cells formed from a morula.
    Germ layers : Basic layers of cells in the blastocyst from which all adult tissues and organs will form.
    Gestation : The length of time spent in the uterus from fertilisation to birth.
    Lactation : The secretion of milk from mammary glands(breasts) of the female.

    A bit messy, but think that's everything there.

    Whats every ones plan for after the leaving anyway? My first plan is toning my body into a weapon of inhumane destruction and death so that no bullies will dare tease me or mock me when I go to college or else they will feel my pure wrath.

    I also plan on getting the snail from "Adventure Time" tattooed on my left ass cheek.
