Someone plzzz help me!!! Im predicted an A but looking at this paper i've only got 51 marks. How many marks do i have to get in the calculator paper just to get an A overall?
It really depends on mark scheme, but you're probably looking at 85+ I'd say. Could be wrong though.

I got the right answer for surds, but then I saw the question asked for "exact area" so I thought it had to be a number; and I found a wrong method to get 1/6 .
The answer was 3-√6/12, how'd you even get 1/6 lol
3. Does anyone know the overall mark to obtain a C?

This is a maths teacher's worked solutions!
5. anyone got anything for 3hr
6. do you know what the grade bounday is
7. For question 22 I only got X=6 so would I still be able to receive full marks or not?
8. what is the grade boudary to get C and i think i got 14 marks on this paper
9. Thanks 😁

Grade boundaries for C on the higher paper are generally between about 57 and 65 over the two papers.

No you won't, probably 2/3

which method did you use, was it trial and error?
13. I got x=-18 and x=-6 for the quadratic question

It really will depend on the level of difficulty with Paper 2, hence you may need anything from 74-88. This first paper wasn't the most difficult in recent years, so the upper number will probably be closer to the requirement.

Suggestions
Focus your efforts on the high end (A* and A) calculator questions. Ensure you don't lose silly marks in the earlier questions. Forget this first paper, it is done.

Good luck
15. How many marks in each paper do I need to obtain a C, overall?

73 is 100% an A, what grade boundaries are you looking at? 😂

Did you get
3x^2 - 24x + 36

If yes, you should have then divided 3x^2 - 24x + 36 by 3, then found the factors. I believe you found the factors of 108 (3 times 36) and sum of -24.
18. the circle theroms one was 90 degrees definatley

in question 5 for the amount of days the oil in the tank would last, i rounded 892 litres to 1000, so my end answer was 1000/20= 50 days instead of 45. would i still get both marks, despite not rounding to 900? someone told me you must be specific

Around 80 marks you should be aiming for
