The general consensus is that 105 mins was correct. You had to take 30 off as it asked how much longer.

What do people think the grade boundaries will be like? The march paper was 168/200 for an A* but it was apparently much easier. Would it be feasible to guess 162-3/200 for an A* this time?
I'm sure the grade boundaries don't go down , they increase or either they stay the same?

The Second Equation, is bridging onto AS-Level, and I've never seen it in a texbook :P

I doubt we need to know it, only for circles about the origin!

13. As a estimate - how much marks do you need to get an A grade in maths
14. Jesus! Just looking at the November 2012 paper calculator, if tomorrow is as bad as that then I'm screwed!!!!

write 2x/2x-3 - 7/[x(2x-3) as a single fraction in its simplest form.

If you could give me the steps on how you did that would be very much appreciated!

Aim for around 150. Did the answers for tuesday's paper help?

128 is my prediction - it was easier than November 2012, a bit harder than March 2013 so that's bang in the middle.

Subtract what you think you got by 130 and go for that number to ensure you get an A.
