You're aware that the 80 UMS grade boundary in June '09 was 55/75 right?
I think this feels like a 59 - 61/75 for an A. I also don't think I made the cut. Hopefully C1 and C2 can bring me back over the line though.

Yes, that's because the June 09' paper had hard questions throughout the paper one after another non-stop. Apart from the Moments and maybe SUVAT/Speed-time graph question the rest of this paper was relatively straightforward given that someone had gone through all the papers and solomon's.

for the last question, i got A right. but for B i stupidly got the tension wrong. so when i did C i used that tension but i did the right method. how many marks would i get for last question.

Yep I did the same one!! Do you remember any answers?? I found it difficult (mainly time pressure though).

Ahh not exactly. I have a feeling all my answers are wrong :frown:

that's why I've been looking for a markscheme but everyone seems to be only talking about the paper that Arsey put up.

I think for question 2 the tensions were 7.something and 8.something and according to some people the R for question 7 was 1700(or something close).

I found the first question. I don't know why I couldn't get the answer, I tried double checking with the total momentum equation but it didn't work so I know I'm definitely wrong there. Think one of the speeds for the particles in question 1 was -2m/s

And the mass, again according to some people, was 20.something? :confused:

I'm an international student and haven't done the paper you're talking about :confused:

So that's how we're stopped to cheat... in the past after every exam, everyone had to go into isolation where we couldn't have phones, computers, etc... This year they tell us, there is still isolation, except for maths and sciences....
I'm like: Wha???

If the papers are different across different time zones, then it makes sense.

I'm considering starting a new thread for M1 international students. Though does anyone remember any questions to get us started off?

I remember the one with the tensions in the strings. I think the weight was 8 and the angles were 25 and 35. Also the one with the ball being thrown one from 50m at 2ms^-1 and one from ground at 20ms^-1 and we needed to find the time when they're the same height.

That's about all I remember :/

SUVAT was my downfall, Where do you reckon 90ums will be ? I think I got 64/65 out of 75

Does anyone know how many follow through marks would be awarded for question 6 if I got m as 30 instead of 25 and therefore a wrong distance and used these throughout the question with a right method?

You may get ECF (error carried forward), unless there is a DM1 (decision mark 1) on the paper depending on your answer. ECF probably will only get you 1 or 2 more marks though

Made one ridiculous mistake, for question 7a I calculated the velocity as (1i-0j), irrespective of this wrong answer I calculated the speed as one normally does (square both the i component and j component add them and take the square root) How many marks will i drop?

The tension one I got something like 7.6N and 8.4N. Not sure which one for which.
The one with the two balls, I got about 2.8s and about 17.2 m

You remember what you got?
