That's okay, no worries. Glad it helped. I don't know if I did enough for the A* though unfortunately

5. QUESTION:

for 2bii

would there be 4 solutions for x as it's sort 29, therefore +-?
7. Great paper! I stupidly didn't read the dif eqn question properly and didn't see x=0 t=0 so I didn't solve the equation, I just left he constant of integration there. How my marks will I lose for that? Spent the last 20 mins trying the last part of vectors instead of checking my work overall I think I got 65-69/75. Will that along with 62-66 in core 3 be enough for 180 ums?

Grade boundaries seem to be a complete mystery this year, but yeah, it seems you'll get 180 with that, especially if you get the higher marks of that range.

I did the same thing?! It was very sneaky not stating that x=0 and t=0 ..
Hah I did that too, did it even say x=0 t=0?
10. Those saying they got 73/75 should minus 5 or so marks in reality

What this paper easier than last years
11. Guys, 65 in Core 3, 62 in Core 4. Been an A* for June 11 - 14.

Think this will get me an A*?? please, ANYONE?

guys, on 7B which is a 6 marker, i forgot to differentiate y in the chain rule, i mean i did right but forgot to write down the y so i got 7/4, how many mark will they take out?
I did exactly that, don't think it will be too bad

Correct me if I'm wrong, but I think full ums was 65 in c4 last year. In my opinion this paper was very similar so you should be good

CD223 mate, might be worth double checking vectors part incase im right, but tbh the way todays been I doubt it lol
What did you get for the vectors part b and c? Did you use lambda as 4?
15. How much ums would 55/75 for core 3, 56/75 for core and 67/75 for stats 1b get me like estimate?

judging from everyones reaction it was a lot easier than last year. threrefore A* for c4 is probably the same as june 2010 which was 67. I personally found this years harder but seems like not many people did
18. Also for the differentials question, I put t into terms of x instead of the other way round don't know what as wrong with me. How many mark lost you reckon??

hope so

It was an easy paper, no doubt, but literally everyone has made a ton of mistakes. People in my class IRL are incredibly clever and have all dropped a ton of marks from random places.

And after all, grade boundaries don't necessarily represent how hard the paper was, just the average results of the people who took it.

I think this is an easy paper that most people have not done so well in.
