Hi guys I was just want wondering if you lose marks for saying extra stuff (even if you gave all the necessary parts)? Because my strategy for long responses right now is to just dump everything I know in that might be even remotely relevant to make sure I cover everything because I've found...

I wonder what that feels like.

Guys I was wondering for Q14b part iii, I proved f(x1) is negative and f(x2) is positive therefore alpha is between x1 and x2, but I forgot to prove x2 is greater than x1. However I remember in part i I explained that alpha has to be greater than k (which is x1), so could it still count?

I have a question. If you crossed some part of your working but it's still readable, and then you draw an arrow to it saying you didn't mean to cross it out, will the markers still consider it?

The question said without calculus so I don't think stationary point is important.

I think so. In 2013 88 got scaled to 97.

Will he post it here?

It would be pretty badass if they conjured up a question that combines every single topic in 4u into one question, as a final send off for the syllabus.

Interesting. At our school everyone did a second hand investigation and found it really easy. The one guy who did a first hand investigation came last in his major work.
