For the vectors one. Did anyone get numbers which were all over 3 for X
Found it quite a messy paper, but it wasn't overly horrible. Did everyone remember to discard the spurious solution in question 2?

Oddly, the vectors question was one of the few questions i could do.
Ive almost definitely failed, ill scrape a merit at best.
It wasnt part of my offer though so it doesnt really matter.



Lambda = 1.5, mu = 1.3333?

could someone help?
I'm in year 11 an I did this seeing as it was the last year. Now I think I got 57+ method marks so my question is if I fail would unis look down on this


No.Merit in y11 is very, very good

I found that 0.5 worked

It did, and x=-1 had to be discarded. Was that 9 marks?

Erm no...you're in year 11, for the vast majority of people it wouldn't be feasible to take it at that stage; they either won't care or will see the fact that you entered as a positive
edit: and if you get the merit then it'll look fantastic

What was the answer

What was the answer


I think it was something like (10/3, 11/3, 7/3) or (11/3, 10/3, 7/3).

would I lose 1 mark for not discarding x=-1

It may be one of the S+ marks, but you wouldn't lose any of the ordinary marks as part of the question.
Did anybody get sqrt101 / 2 for |AX|?

If I got different methods with different answers one of which was correct, would I get marks

Do you mean different answers with different methods? :tongue:

But one was correct

Should be fine. The people marking the paper will take into account the possibility of unorthodox but correct approaches to tackling a question.
