I see many people found the area question hard but i don't understand why. If u just find where L1 crosses the x axis that creates a big triangle, then minus the small triangle (between where L1 meets x axis and x=0) from the big triangle.
Quick question, for 7, when simplifying y=, (the equation before you dy dx it), we got taught that 7/3x^1/2 would become 3/7x^-1/2. So I don't know whether I would have got full marks on that questions. What do you guys think?
For q10 i got 3x+5y-45=0 therefore ive got ×=15, i did all the methods right how many marks would i get ? Also for q11 i did all the methods right and my answer was P (-2,4) therefore leading a wrong answer to part c but methods right ?
I thought it was a reasonable paper, expect standard boundaries.
Some of the fractions were a little odd. I think 8a will cause a lot of problems.
I would guess at 62-63 for an A and 55-56 for a B.
I'm guessing mid to high 60's, so i'm not that upset with how I did... I feel like no amount of revision could've prepared me for the area question, the last part of the arithmetic summing question and the first part of the discriminant question, because, there have never been questions like that in any past paper before. Overall, considering, the mark scheme and the grade predictions though, i'd say i'm pleased :P .
I took the exam 2 years ago actually *blushes*... got an U (overall) and had to repeat the year! (without Maths hehe) Just wanted to distract myself from my current exams, I don't take Maths anymore!
For the quadrilateral question, what if you got the area of the trapezium right but you did 35/3 x 3 instead of 35/3 x 7 for the triangle. How many marks do think this will be? My overall answer was 186/6.
Perhaps not as bad as initially thought but I definitely think it was worse than last year's paper.
For the area question I gave a few solutions, the last attempt I did get 163/3 but I didn't cross the others out and I'm wondering the marking policy regarding this? The other attempts were incorrect.
Fact: Never cross anything out in an a-level maths paper. If you take multiple attempts in a question just clearly label attempt 1, attempt 2 etc. Examiners mark each attempt differently can consider the one that awards you the most mark. Do not cross anything out in a maths paper especially if you get two different answers and you don't know which one is correct.
I emailed my teacher and she said that i would have lost two marks for an incorrect k and everything else is ecf so you probably lost the same as well if it was just one silly mistake like + instead - or something
@Arsey , @TeeEm , @Puddles the Monkey Any of you make S3 (Edexcel) unofficial MS? Its next week on 25th of May. Or do you know anyone who does it for S3 exams? If you found anyone next week (and remembered this message) let me know on 25th of May. Thanks!
