    It is videos GCSE questions (2016) and you can print of the questions and do them when the person is doing it so you have a better understanding on questions. It has boosted my grade by 2 full grades it is worth it trust me.

    The following are some of the most difficult maths questions you will ever see on a GCSE paper (I thought it was adequate to share these judging by everyone's resent to Hannah's sweets - though I found this very easy). I found all the below questions simple as well so do ask if you get stuck!

    Do you think I'd be able to revise enough practice papers for the next 1 week and 4 days before the mom calculator exam? >.< I'm seriously getting a bit worried about not getting the grade as this is for my first choice university and I haven't been taking enough past paper.
    Dont think about uni etc for now ur just gonna worry yourself and plus uni is a gd 2 years away(im assuming ur 16 btw) take each day by day and just do the past papers and mark them with the correct answers,do not think about anything but the questions your given this way you will perform at ur best

    Sure!

    So that I do not remove the overwhelming satisfaction of getting a really hard question right, I'll give you a few hints:

    If the following does not help, just ask for more help!

    Imagine that h=y and t=x.

    You now have a quadratic equation.

    Identify where the highest point of the quadratic is and find out its y-coordinate.

    This will tell you the highest point reached by the ball.

    A diagram may help

    Struggling on the last one.
    That is probably the hardest question out of all. Here are some hints:

    If this does not help, ask for more

    Firstly, identify the different ways of getting a total score of 4

    Then, determine the probability of getting a 4.

    To do this, notice that the probability of getting a 2 for example is 2x/360 (angle of segment over sum of angles, which is obviously 360 degrees)

    Then create an algebraic equation in terms of x - remember the AND / OR rules.

    We know that the this algebraic equation has to equal 16/81 (as given by the question).

    Then, all you have to do is solve for x - you should end up with a quadratic by the end, which you can solve .

    Hey. Did you guys have a quadratic equation which simplifies to x^2 -360x +12800 = 0

    Which gives you x = 320 or x = 40?????

    Hopefully I am right!

    Still a bit stuck;

    Would it be 2x/360 X x/360 = 16/81

    Personally I found maths easy to get an A or A* provided that you practice very hard beforehand on many different types of questions that may require you to think strategically to get the answer.
