This is a bit vague?! Do you mean instead of the normalised eigenvector?!

Most likely for (b) you will, but you won't lose any if you normalised for (c), as this was required P was orthogonal

For vector question, if I use A as my position vector, is it wrong?

No! The line through AB is not unique - you could have used A/B as the 'jump-on' point or any other point on the line - therefore an infinite amount of solutions.

You could have had the 'unit of movement' to be any multiple of itself also

I honestly don't think they'll be as low as last years!

Yeah, that's what I said! Are there any unofficial predicted boundaries floating around?

Cheers for the solutions
How many marks do you think I'd lose on 8a/8b if I accidentally used the wrong formula for finding the value of e/directrices/focii? (I used hyperbola instead if ellipse)

For Question 8B, I did the whole question using the general focus and ellipse equations and not using the exact value. Then, I ended up with 2a and subbed in my a = 2 at the end, would I still gain full credit?
