AQA Core 4 - Monday 10th June 2013 (AM) - Official Thread

Can you remember how many marks the 'find the co-ordinate where the line crosses the x-axis' in the parametric question? I think I wrote x=2, instead of x=-2, so the next part was wrong (I did the method right though).

This is where I lost my marks;

- Last part of the Vector Question. I just found length AC and wrote A=1/2absin(c). I'll probably lose all 4 marks though.

- I couldn't find the k value in the dh/dt thing, so that will be 1 or 2 marks lost.

- Then the silly mistakes in the parametric question have probably cost me 4 marks maximum.

I think I'm about the same as you, with a worse case dropping about 10 (should be less, but you never know). I need 92 for an A* so it is definitely possible. Still, was a tough exam.

I think you guys are all being far too optimistic about the boundaries.
I really wasnt that hard of a paper, i had it all done in 20 mins other than the last part of the vector question.

FP3 was alot harder.
its probably going to be 65/75 for an A

From the part just before it, did you get C = 2?

Anyone else get final answer as 4.25metres?

2 marks to find co ordinates so assuming you got y=12 then you'll only drop 1.

You lost marks in basically the same places as me.
Only found one of coordinates of E, with no real workings (drop probably a couple)
I put ${10\over3}\ln2$ instead of ${11\over3}\ln2$ which will cost me a couple.
I also like, you, got k wrong in dh/dt (which is probably one, maybe 2)

I also used $\lambda$ as the variable for the line between A and B, I hope this doesn't cost me, but it might.

I think the k value may only be one mark (but potentially 2, if they don't reward dh/dt). This is my reasoning;

dh/dt is one mark.
k is one mark.
a is one mark.

Well, I think you'll need like 62-63 for an A*, so hopefully you (and I) have gotten the A*. Good luck!

20 minutes? If you're going to lie to show off, at least try to make it believable.

Don't worry - I'm sure they probably carry errors forward! It would be so mean of them to make you get the rest of the question wrong.

I say 20, it was probably more like 19/19.5.

If i was going to lie i would come up with something far more entertaining. Like how i was abducted by aliens the night before, called out to assist the Avengers the morning of, and then still got there on time and finished it in 19 minutes.

I am being deadly serious when i say i had it done in 20 mins.
I think having done FP2 and FP3, the core stuff is just piss easy in comparison.

Dont be mad.

I did fp2 and fp3. I still found this hard.

^ I did FP3 today and it was piss easy compared to C4... WTH!
