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.

Just looked at the answers and realised i stuffed another 2 marks up.

Should get like 94 or 95 raw

What do you think band six cutoff will be.

 

[Mr_Kap]

83?? or 84?? or 85??

 

[qwert73]

What do you think band six cutoff will be.

hopefully mid to high 80's

 

[Mr_Kap]

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%

which region did you shade in?

I cant remember which one i shaded in

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?

no it is greater than or equal to as it didn't say distinct.

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

There has not been a single 2U exam with a band 6 cut off at the high 80's.

no because delta=0 is real too, it's greater or equal to

The left side... I also shaded the part to he left of the y-axis which isn't shown in the answers posted earlier

were the asnwers right or are you because I got the same thing as you.

There has not been a single 2U exam with a band 6 cut off at the high 80's.

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

i did this too, are we right?

 

[kenny777777]

i shaded within the 1st and the 2nd quadrant :/ also bounded by the x axis

 

[HecticSandWitch]

I am almost certain this is correct, it is inside the semi circle to the left of the line.

 

[SlimiJay]

[qwert73]

i am almost certain this is correct, it is inside the semi circle to the left of the line.
