Any ideas of even approximate/percentage based grade boundaries lads? Hoping for a slick 55% for an A but in reality is it something like 80%?

I think 70 percent will be an A and then every 10 percent going down is one grade down.

I did the edexcel version of that exam today, it was diffucult and had things we hadn't even learnt but they expected us to simply figure it out with logic. I revised a bunch and I got 92 marks in the mock test which was 1 week before this exam I did today, but for the real exam I did today, I will suprised if I got 40 marks out of 100, that's how diffucult it was for me atleast. if everyone found it hard then hopefully grade boundaries will be stupidly low

This exam was so ****ing hard. What was that curve integration question. Did anyone get like 1.22N for the friction of the boat.

Haha yes 😂 and the only question I could do was question 1 the surds one and question 2 the binomial distribution and 3 for which I got a=-4 and b=12 which is what my friends got too. I missed loads of the others out or I just wrote nonsense for the sake of writing something the questions were so difficult and none of the past papers before have been anything like it. The stats paper best had be easy otherwise I’m going to fail

What did Everyone get for the friction of the boat. I got -1.25ms-2 for acceleration and then my friction for the boat was 1.2 something.

Okay so first of all I didn’t have a clue with that boat question and I didn’t get an answer or even 1 mark so ur not alone 😂😂 and yeah that curve question ur right I kept getting -2 as the y intercept when it’s minus 4 but then I did something and ended up getting 3/2 as the area but I don’t think that’s right. The exam was sooo difficult I swear it was nothing like past papers and literally every question was impossible apart from the first 3. And yeah for 3 i did f1 + f2 = f3 and just figured out what a and b was using just general equation rules I think it was something like a = -4 and b= 12 is what I got. I got none of the mechanics right and I could hardly attempt any of them, that test was impossible

For the Logarithm question the equation was Y=AX^b. Then for the next question you just ln both sides and then you get the equation in ln form. Then the 4 significant figures was meant to be like an e.g 5.434 that is 4 significant figures. Then to find gradient you just do the change in y over change in x, The Question about the curves C1 AND C2 you need to differentiate first equation plot zero into gradient function and it should have gave you -4 as the gradient. Then you do y-1=-4(x-0). That is the equation of the tangent. Then you need to make that equation equal to the curve C2 and then you do discriminant.
