any ideas on the approx. minimum score over both exams to get a 40 ss?

[Zues]

I made 2 really stupid mistakes in exam 1, like misread it. Is losing marks on exam 1 worse then exam 2? and provided with a 37/40 on exam 1 and a 60/60 on exam 2, what sort of score will i be looking at? Rank 2 in a quite a strong cohort.

Thanks

Wouldn't question 2 in matrices be C?

The only vertex that can be reached from vertex Y, is vertex D. Vertex C cannot be reached.

Can someone please help me with what study score I'd be looking at? Ranked 1 in an average cohort with an average of 98% on SACs and I got 35/40 for exam 1? (made some stupid mistakes!) Thanks

Low 40's depending on exam 2 score

Technically marks on exam one are worth more than those on exam 2, but the difference is marginal. You would still be looking at 45+ with a 60/60

Hi All Has anyone got a copy or a link to the questions please.

Just a question - on the answer sheet it made us shade the box of our  chosen modules AND write it down in the box provided.
One of my friends ticked the box instead of shading it..........  Will this matter in the process of the exams being marked as they are marked on the computer? Or will it be ok as we also had to write it down?

I think they made you write it down in case something like that happened. It should be fine

I have a question regarding Q9 of Core -

I did the equation and got -0.005, however, surely fuel consumption plotted against the weight of a car would be a positive slope?
E.g. wouldn't fuel consumption go up as the car for heavier and vice versa?
Thus, I gave D as the answer instead of B... what do you guys think?

That's what I thought. But I've been to lectures and they've said not to rule out an answer just because it doesn't seem probable in the real world. It would have had to be a negative slope because the information we were told lead us to that conclusion.

Hey DAN, how did you get question 9 in bus maths as E shouldnt it be D

D is what happens when you don't count the interest apparently.

[happily]

sorry i meant question 1

it goes through each vertex once, and does not return to the original vertex, hence a Hamiltonian path
