I got that too.. I also thought it was unusual numbers :/

Grade boundaries will be high I reckon, was a 'easier' paper, I think I dropped about 4 marks(at a push) and the majority of that was the the show that, I can't remember much but stuff like k=7/2 and B was nine hundred and something b=1/9a-5/9 the other logs question X= -2.19 and 0/no solutions, sinx= 1/4 or 2(no solutions) and solve and minimum perimeter is like 120m or something once you solve dP/dX and X= 16.6 something, radius of circle is sqrt 34 and I can't recall much more


sinx was -1/4 was it not?

It was a pretty accessible paper I reckon
I think I just spent to oblong showing my working, probably could've got more final answers

i swear b was like -7000 and something, can't remember off the top of my head and k was -16


k = (+)16
b = 936
Yes i got that

K= 7/2, b=936

I think a lot of people found it easy so UMS coefficient may be less than last year which was 0.95 x ((Raw mark/75) x 100)


I'm not sure, lots of the people on the TSR threads are getting blatantly wrong answers. Easier than Core 1, probably 62 for an A

That's correct
Really nice paper, second part of the log question was the only bit i think I messed up.
I didn't leave my equation of the tangent in the form ax + by + c = 0
I left it as y = (-3/5)x + 19


How many marks will i lose?
