Reasonable paper I thought

Boundaries

Jan C3 boundaries have been fairly consistent in recent years; 61, 59, 60

I would say Jan 11 (61) was the most challenging of the 3.

I think Jan 12 was significantly easier than Jan 11, so I can only think that the boundaries will increase


My best guess is....


75 = 100UMS
69 = 90UMS
63 = 80UMS
57 = 70UMS
50 = 60UMS
43 = 50 UMS
36 = 40UMS

thanks

thanks arsey
what you think the grade boundary will be?

[CMPUNK]

for q1 if i forgot to simplify how many marks would i lose

[dude345]

Will I lose a mark for leaving my answer as 28 minutes (to the nearest minute)

[ahmedgul]

thanks

[Beckiix]

I think I got a high B or a low A ><

Got time = 27.7 for the one question but didn't add it on to midday :/ grrr.

[kanasaki]

oh yeah 1 mark off
domain of f^-1(x)

74/75 done

[annagoesbroom]

If I put 2 extra solutions for question 5, am I likely to be marked down?

[maths134]

Thank you! 75/75 if 28 minutes past midday is allowed lol.

[Patchey1000]

75/75 reemo

[letsdothetimewarpagain]

What's your guestimates for grade boundaries?

Made a stupid mistake on the second differntiation question and a couple of others

Think so

[YawningAngel]

Concurred with the model answers on all questions, guessing a slightly above average grade boundary since a couple were trickier than usual.

Arsey - do you think there will be any mark lost for putting that t= 28 minutes to the nearest minute instead of 12:28 as an actual 24h time? Otherwise full marks!

[thomas93]

74... Damn, 12.28, what a cursed time!

For the normal to the curve, i got the correct x coordinate, the right dy/dx in terms of y but somehow worked the gradient out as -1/2 not -8. After that i made an equation using that gradient. How many marks will i have lost?

Got everything else right except the domain, i didn't know what was going on :P

Thanks Arsey Just confirmed my suspicions that I mess up Q8 but very very surprised but happy to find out that I got that 10 marker right Few silly mistakes... time in minutes thing... but other than that alright.
Grade boundary predictions would me greatly appreciated if possible!

Not too bad
