Mr Kibria, the guy who did the unofficial mark scheme for paper one (with all the questions, answers and number of marks) has said he's not doing one for the second paper :frown:

for (Q19) i got 10.89 and i thought you cant round up people so i put 10, was it definitely 11


My teacher told me the mark scheme may allow both as they have in the past, but the best option was to go for 11.

I got 40.0?


same!!
even my friends got that
now I'm not so sure if i even did that well
:frown:
For q24a everyone seems to have got -1/3x+4
But i got 1/-3x-4 which equals the same if you sub in any x value. Will i get the marks?

i think both answwers would have been accepted because theyre both the same thing
i did the -1/3x+4 one though just to make sure xP
Guys I'm going to have a heart attack. For the love of God can someone please tell me that around 145 is a secure A ? These really high grade boundary speculations are killing me.

Could somebody tell me how many marks each question was worth
What are the marks for each question?

Rounding during the working isnt always reliable. you should get 4-5 marks for method. but its the rounding which could bring you back a mark or two. nothing to get too worried about

No i didnt round. Im saying that i used the exact values and got 80.3

According to this mark scheme most of my answers were correct looking at around 70+

Does anyone have access to the paper, or know how much exactly each question was based markwise

Wasn't the last question like 1/2 * 7 * 8 Sin(X) = 18


56Sin(x) = 36

Sin^-1(36/56) = X

x = 40

???

I think I did it wrong then.


yeah, it was at first but then I think you had to use the cosine rule or something to get the other angle. I also did that thinking that it was the correct method but then in the last minute I realised that I hadn't completed it.... you'll get some marks though so don't worry.

I think the reason why people got 80.4 or 80.1 on the last one was down to if they rounded each digit they got for each step of the answer. I got 80.1 and I tried to stay as accurate as possible, but whether people with 80.4 rounded up or down or the other way round I don't know?
just everyone stay chill lol BC nothing we can do now, stay happi & positive dudes X
I think I got 145/200, somewhere around there. Do you think I will get an A?
