    Best way to do well in the leaving cert? Avoid as much competition as you can. Hebrew studies here I come

    Continuous assessment is the only way in my opinion. If I've worked for the last two years I don't think they can determine my ability from one exam.

    OFFICIAL BOYCOT, TWEET THIS TO ALL YOUR FRIENDS:

    This year the SEC has gone too far and made exams slightly unpredictable.
    As a result, we must make sure not a single examiner is paid after this intolerable scandal.
    On Monday, 9:30 am, not a single soul from the 40,000 students must attend their exam centre until the SEC apologizes and hands out A1s to everyone in the country.

    Thank you for your cooperation.

    It's a straight line through x=1
    Straight up.

    Guys this is a really special post for me, it's my hundredth one! Better not waste it! :p


    Well, I've grown to love the entire leaving cert forum over the past few months, but I'll probably regret the hours of study it's taken away from me for study next August.

    I hope everyone on this thread especially gets what they deserve. I've seen nothing but compassion and gratitude, you guys make it hard to believe the LC is a competition! :p

    The SEC can take our predictions, but they can never take our souls! LC 2012 are a generation to be reckoned with! ;)

    X=1, and use any value of y as the line will be vertical and will pass through every single value of y. You could let y equal 74434673/22134 if you wanted, but it's easiest to go with 0 and 1 :P

    Does anyone know if there's a way I can do standard deviation on my calculator, and will I still get the marks? My calculator is a "fx-83GT Plus".

    You are absolutely grand doing standard deviation on the calculator, they expect you to and you'll get full marks. I have that calculator too, it's a bit long but here's how.

    To input data values:
    Use shift > setup > (down arrow) > 3.stat to make sure frequency is OFF.
    Then:
    mode > 2.stat > 2.A+BX > enter your values (use = to go down a row and the arrow keys to go over to the Y column when you need to)
    When all values are in press AC.

    To get the standard deviation:
    Shift > Stat (over no.1) > 4.VAR > 3.sigma-x > =
    this should give the standard deviation.

    You can also use option 2 within 4.VAR to get the mean, or A and B within 5.REG to get the y-intercept (A) and slope (B) of the line of best fit.

    PM me if this gets confusing or you need more help :)

    Thanks :) and can you just write the answer, you don't need like any other work to be shown?

    Unless they specifically say 'without using the calculator' (which as far as I know they shouldn't), you can just write the answer.

    Been doing maths for like an hour two so tired of it.
    I nearly gave up at one point but forced myself to carry on.
    Figured I can do the co-ordinate geometry and the circle if I focus and don't start stressing too much lol. And context and applications I'm not sure about the rest.

    One of the greatest movies ever made, if you have time watch the whole thing, if you don't, take a moment to procrastinate and experience the beauty that is "The Rockn rolla"
