    I should think so. I'm not too sure whether you'd get 7/7 or lose a mark for the second part however, I haven't studied maths mark scheme as much as with science subjects lol

    You will lose out a mark on final answer A1 so 6/7

    2 marks max or given its correct in radians maybe 1
    Marks were for
    Identity
    Two brackets
    Cos= -1/6 and 1
    Two marks for correct solutions
    Radians loses one
    In all serius maybe lose A1,A2 for the answer been wrong unless it falls into special case aqa should just use graidians all the time

    I'm so confused😅 Do you remember the coordinates of A and B and then the line equation? I'm gonna attempt it but vectors are evil so I'll probably mess up
    I can't, sorry!

    Someone help me by telling me the method to the part c of vectors tyvm i think i got it wrong :c.
    So how i did it was using the point of intersection (which i called Q)
    lAQl=3lQBl (those are mod signs )
    got mod AQ as 140/3 then as you know b lies on line L2, you do line L2-Q and you get a nice little quadratic which gives lambda values, then just sub them in

    Was the direction vector of l2 (3,-5,-1) or (3,-5,1)?

    I did it again and found mu as 1/2... I reckon we might have found vector AB incorrectly? Possibly writing OB and OA the wrong way around?

    Ffs, would I only lose one mark for getting costheta as 92/140 and not 52/140 as I got the sign wrong?

    Would I get a mark for finding the length of CD for 6c), or is that irrelevant?

    I messed up the coefficients for A and B in first question but i answered the the binomial correctly using my incorrect A and B, will I only lose the marks for incorrect coefficients?

    BTW: Did anyone get 1/3 and 5/3 for lambda values?

    I am in a similar position, pretty much every class test I have done resulted in an A*, but now I don't even know. Will your university place be affected?
    Mine will be. I have a 2A*A offer from imperial and after these 2 exams which were not just hard but unfair, its pretty much over. Especially after i had a nose bleed in my chem f324 exam. Been a terrible week.
