Edexcel C3 June 2016 - Unofficial Mark Scheme

Scroll to see replies

I have 0 faith in those gold papers now. I did them all yet they were way easier than actual past papers + the exam we just did. Q9 on this paper completely baft me out :frown:

. I'm just going to do regular papers for C4.

Fair enough. I was lucky to have done June 2007 before this paper, which had an incredibly similar question to 9. Solomon papers are meant to be good for learning around the topic; there'll be something not seen before on Friday and they might help anticipate it

I'm expecting grade boundaries similar to last year's, anyone else? Looking at here I think best case scenario is that I may have picked up 70/71 marks depending on if I lose a mark for not simplifying 0.5ln(6.25).... plus the last 4 marks :c

I did the exact same as you but sort of got part way through last part of last question, got a =5 but not the inside part so maybe 1-2 marks.

That can't amount to many marks lost - sounds like you still have an A depending on method marks. Anyway, not much you can change now, I'd recommend doing a lot of C4 and trying the Gold tier papers http://www.physicsandmathstutor.com/a-level-maths-papers/c4-edexcel-bronze-silver-gold/ which consist of the hardest questions and increase in difficulty as you go up numbers. Have you got S2 or D2 next week?

Ive done literally all the papers for C4-Edexcel, solomon, ocr,ocr mei, IAL even like idk what else to do for revision tbh ... i have s2 but *****ing it cause i had to self teach it all and the grade boundaries are ridiculous

I think it might just stay the same tbh - i think there were a few dodgy questions like the iteration one where people got really confused ( including me :/ )

so annoyed how i drew cosec graph for arcsin :angry:

i doubt you're the only one - the arc graphs are the sort of thing you skim over and don't bother learning

Think i secured atleast 50/75 while looking through the MA and trying to remember what i wrote
Should of done soo much better oh well looks like ill be on the solomon paper grind for c4

Ok guys, please tell me how many marks you think i lost for each of these errors.

Left the answer to 7b as the exact value which was sin(-pi/3) - 1

Forgot the other 2 points in question 8(b) but showed + and minus etc

Managed to get to the 3rd stage in answering the very last question but couldn't work out the final form.

Didn't write any answers in for + and - ve in question 4d but did mention the correct numbers for the interval, talked about the change in sign and the root in the interval between (x and z) etc

Used 90 and -90 in the arcsin sketch

These are all the errors I made in the exam, how many marks out of 75 would I get?

Any insight is appreciated greatly

How accurately did people predict june 2013's grade boundaries?

this paper wasn't that hard

Exactly what I did :lol:

I deliberately learnt the inverse trig graphs yesterday because I suspected that they would come up; clearly didn't help. At least it was only 2 marks.

i know that! Just seeing how good we are at predicting dodgy exams' boundaries.

same man around 50'ish, hoping the grade boundaries are that of near 2013 which gives us a chance of a B. but we could slip into C grade :redface:

oh sorry i get you now, i means as with everything online, take it with a grain of salt. best thing to do will be to focus more energy into c4 than worrying what exactly you need to get, getting close to 95% in c4 will get you what you need most likely and you can get that good in two days if you bang it out
