Some of the later 2016 ones are a bit tricky but nothing too taxing.

Trying to think of a way to get A on its own was the hard part of the last question

I got k value for -9/4 (simplified)

I think you had to work out the gradient of the second equation which was 6, and then use -1/6 as the gradient when you work out k because the question says normal.

Also, this may seem dumb, but I thought rational number meant mixed fractions. Would I lose a mark if I left my answer in mixed fractions in the 1st question?

Also what did everyone get for the last question?

I got k=81 as it was parallel to the normal and I didn't think I had to find the -1/gradient of the normal.
I think I got K= -8.5/3 lol
Having experienced driving a rusty green mid 80's vauxhall I am qualified to say that this test was extremely unpleasant
That paper was OKAY , I have a feeling that there was some question that I messed up on ! But anywho. Gotta wait for C2 and S1 now !!
The questions made sense however I just got to breaking point and froze on some questions because of the immense pressure. And now I just feel like that this is the final chapter.........................
