    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

    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

    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...

    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.

    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?

    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.
