It always happens tbf!!! Marks are so easily lost in exam conditions under pressure! The papers are way easier to do at home in a calm environment with maybe a bit of motivational music

Now just repeat that tomorrow
I'm going to get stressed and drop stupid marks, I know it :/
Let's both just hope for the best
What's your rough score from the unofficial markscheme from C1? I think the A boundary will be about 59 for that, so that 90UMS would be about 65/66. I think I'm on 64 but it depends on what I've remembered right

You have to use a point which is closer to the point that you are trying to find the gradient of.

How the heck do you do the 'closer approximation' ones with the gradient???? I don't know which points to use
So say you are finding the gradient of point A and you are doing this by finding the gradient between A and B. You would choose an x value of B which is closer to A. Say A is 3 and B is 3.5, you find the gradient between those points. but to get a closer approximation you would choose a new point for B such as 3.2. so you would find the gradient between 3 and 3.2. this gives you a gradient that's a closer approximation of the gradient at point A.
sorry for the bad wording!
