# Edexcel A2 C4 Mathematics June 2016 - Official Thread watch

1. For question 4a) how many marks will I lose if I simplified it wrong
2. (Original post by fefssdf)
i specifically remember checking whether it wanted exact answer and it didn't so don't panic
I did the same method and got an exact answer, 12/5 so if you didn't get that I doubt you got it right I'm afraid
3. What ums are people thinking for 71 on C3, it was 100 last year and I don't think the paper was particularly harder than that. Despite this I would be surprised if it was 100, hope it's over 95 tho
4. any guesses on A boundary for C4?

Uhhhhhh spoilers !!!!! XDDD
Oops I'll delete that, sorry... (well I guess it's too late LOL)
6. (Original post by fefssdf)
oh god you might scrape it but you might not...
That's the most agonising part of it all, no knowing what will happen. Hopefully the odds are in my favour...
7. Help with this question please

I believe you've only looked at the first part of the problem.

1) probability p(x>6) and p(x<4) this is for the way you've drawn it on your diagram

2) then we must do the reverse as the smaller sides before could actually be the longer sides.

I'm sorry for the poor explanation. Exam Solutions probably has a video explaining it more clearly on his site

Do they care about +C ? I think i forgot to write it for that question..
They do for some questions and they don't for others - it depends on the mark scheme. So if we say that there were three questions on that paper where you needed a +c (I can't remember how many exactly), then maybe one of those questions will penalise you for missing out the +c and the other two will say "Condone missing +c".

A similar thing is done for rounding when the question explicitly says "to three significant figures" or "to 1 decimal place" etc.

doubt it'd be over 95 really

71/75 just as a direct conversion is 95, surely on the level of difficulty of that C3 paper 71 should be 95 at least?
12. how come there's no marking scheme yet??
13. Hi can anyone remember what the height was for the trapezium rule question as i got 5/2 ?

there is but it isn't very good - I want to see the actual paper again with full solutions but doubt we're going to get that :/
15. I messed up C3 pretty badly think i got 59/60 according to the unofficial markscheme but got full UMS in C4 and have an A overall in As dyu think itl be enough to help me scrape an A*? How does S2 contribute in this btw?

Have a look at grade boundaries for C3 in the past, see if you get 80 UMS or more. If you do, then you are in luck.

The requirement for A* is that you get 180 UMS or more from C3 and C4 combined, and 480 or more UMS overall from 6 units. S2 contributes to the latter requirement.

Thanks just worrried as people found the paper really easy hope grade boundaries for C3 will let me scrape an A
