We’re there 4 coordinates for the 8 marker

i got 5 sets of coordinates
guys how did that compare in difficulty to 2023 paper 3? Do we think the grade boundaries will go up or down?

For the parametric one, if I forgot to sub in my values back into x and y, how many marks would I drop

3 maybe 4

Defo a bit lower imo a* will be 221-222 overall
Ppl seem too happy about this lol does anyone think they ACTUALLY ****ed up? (grade B/C/D, grade A people need to stop acting like their life is ruined 😂)
am i the only one who found comp easier than pure like wtaf some of those section A questions were ridiculously hard

What was the exact question for parametric
How many marks could I get on the parametric equations if I found all the values of theta but just didn't sub them into x and y? (stupid, I know)
What does everyone think the grade boundary for an A will be?
do ym think boundaries will be lower or higher this yr
i got 5 sets of coordinates

Pretty sure one of them was repeated

i got the angle was something like 3/4 pi and 4/5 pi
and then put it back into x and y
Hmm what was the q about? I don’t remember getting such values
that paper was definitely very challenging compared to all other papers 3s

Prob about the same as 2023. I reckon Paper 1 was a bit harder than last yr, Paper 2 about the same. And Paper 3 a bit easier than last yr.

Did anyone else get -73/2 for c on the very last question (comprehension)?

it said c has to be positive. i think the answer is 1

I'm talking about c for the last question on comprehension
Does any1 know exactly what equation they got for the integration by substitution part with the x+1 = u one
