nooooooooooooooo!!!! OMG r they gonna cut my mark if so then how many??????
3. Yeah!! I got that too, but this is probably because we got the upper bound of 4.5 , 4.55 not 4.75
4. Does anyone know the answers to question 3 (the fractions) and question 1 for the milk? I got 1250ml (or that might have been a past paper!)

I think the 5 mark gradient question was 4Y - 3X = - 19

It could also be 3X + (-4Y) =19 , right?
6. (Original post by BOBQ)
you had to give the answer in the form ax + bx = c

The equation for the line was Y = 3/4X - 4.75

That multiplied by 4 on each side gave it in the correct form

which was 4Y - 3X = -19
It could also be 3X + (-4Y) =19 , right?

Hi,
The length of the cube (4.5cm) to the nearest 0.5cm is 4.75 not 4.55. You should get the right answer now
Do you know what will i get if i wrote the whole steps correctly, but the upper bound 4.55 instead of 4.75?

Omg I'm so stupid why am I doing A level maths 🤔🤔. Thank you btw!! I'm actually kicking myself now

It was very difficult, I am going to do A-level but i think the grade boundaries will be around 76% for a A*
if i may ask what is the best age for a levels are you 18+ ?
10. please please what\s this 10.7 degrees question, was it the SOHCAHTOA one?
11. I wrote -3X + 4Y= -19, because it said ax+by=c. It's still correct, isn't it?
12. How was the last Surds question worked out, as i was doing amazing and then that question turned up......, How?
13. (Original post by Martins1)
Yeah, I agree - i have proportionality in my list
can you help me what if i wrote the working out correct but i forgot to write tha answer in the provided gap but i wrote it in the working out space is will i get full mark ?

15. Where is it?

Where is it?
17. Sorry, I would like to know for the mean question if I found 2.95 but I rounded to 3 because it was talking about people . Would i get 3 marks?
18. Would I get 3 marks for the 5 markers on y=mx+c if I found m=0.75 and c=-4.75 but I did not know how to make it in integers?

Sounds like that was either GCSE or IGCSE regional, as we did not have a hard surds question. If you show me it, i can help you do it.
