Math help !!

[hady94]

I was the looking at the mark schemes posted online for Math papers 22 and 42 . I remembered that when I did the linear programming question in paper 4
I shaded all of the unwanted regions so my lines became kind of invisible and unclear but I got the correct region !

Do they give full marks straight away for getting the correct region !

Any ideas , the question is for 7 marks

Yeah full marks, cause they know you understood the lines, and what was required (the region).

Don't sweat it.
