Hey,
Basically I was doing a question today which involved linear programming. I was given a piece of text where we had to pick the constraint ourselves. 2 constraint were given but the other two I had to make (well, using the text).Unfortunately, I got one of the constraint wrong... I know I would lose one/two mark for this but would this affect the other continuing question? So, suppose picking the constraint question is (ii) but then (iii) + (iv) had questions regarding the graph(+ constraint) could I still get full marks using my wrong constraint, or would I be limited?
I am MEI, but of course tell me what other exam boards would do in his situation.
Cheers
P.S. I done my past paper alone, and my teacher is not to good.
