i thought they had a system where if you get the answer and cross it out and they see it they give it?
I'm not really sure whether or not they do.

for the question where you had to shade the circle and the line region thing I didn't find the point of intersection will I get marked dos for that? Otherwise 100%

Here are 2 unit solutions from John Drake from the Emanuel School. I haven't checked them though.
For Q12d, the question said "real roots", so i think it should be delta > 0, am i right?

It is greater than or equal to as it didn't say distinct which means the roots can be the same

Then I guess it will be a mid 80s cutoff.
