# WJEC C2 17th May 2013 Watch

1. awesome Aethecrash, and for the arithmetic had d=7 and a=-20 they were the only nice whole numbers that could be formed and for the geometric i showed the equation and for the first 18 terms i got 491, any 1 else had that at least?

Hi, for the integration graph question i had 58/3, i worked the area of the triangle first and got 18, the area of the triangle i right isn't it or (i'm worried)
I had 18 too so it should be right.

for 3b(i) i had x=5 and for part (ii) i had 21.8, did anyone else get that or....
I had x=5, not quite sure what I had for part (ii), but it was definitely 20 something.

I had 50/3 for the answer. So did several of my classmates.

Does anyone have a copy of the full paper they could post online?

Yep
And relax! Thankyou for geometric series did you get r = -1/4 as the |r| < 1?
14. 180/225. It's 80% for an A.

It depends on the UMS but approx 180/225... which works out at 60/75 per paper

Yes I believe I did Because you had to factorise and the other value for r was greater than 1?..

Yep
19. Oh.****...

I.got.something like:

a = -0.3125
d = 2.625

And it all worked

also integrating I got 56/3

Damn

I'd agree with that! I tried the Jan 2013 one yesterday and had like 71% :/
Same! getting 65% is really not a confidence boost when it's almost midnight the day before an exam was actually pretty good tho - just the 3rd log question that went a bit weird, and i couldn't make the line L intersect with C because i got distracted with working out the rate at which i was working in marks/min
