Arsey's S15 C1 Model Answers (attached to 1st post)

I forgot to put +c for the final answer but I had it in my previous steps. Do you think I will still lose the mark?

for question 5 i graphed the inequality. But since i had originally thought the surd was larger, i graphed 3-2r2 as a negative value, but i got the final possible values correct. Would i lose a mark?

I answered the questions, scanned them, uploaded them.

Sick I got 71 min. 73 max. Made some of the most stupid mistakes ever but should still be decent UMS

There is poll on the official c1 thread already

I don't think you would lose a mark for that. Whether you graphed it on the positive x side or the negative, the possible set of values still must be smaller than 3-2sqrt2.
Some people don't even use the graph method, some just picture it in their head

great to hear!!

Any predictions for grade boundaries Arsey? I figured 59-61 for an A, sound reasonable?

Also, question 5 a, I didn't start out with b^2 - 4ac < 0. I started with > 0. How many marks would I have lost? I ended up with the right answer, I think.
