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

Edexcel C1 2016 Exam chat is here.

Here are my solutions.

I didn't think it was an 'easy' paper, quite a few questions with tricky parts.

Expect average(ish) boundaries.

Edit

The vast majority of questions seem to be about boundaries - you may as well start a thread asking what the weather will be like next week. No one knows, the boundaries are calculated using statistics based on the actual performance of students taking the exam. So it depends how everyone else did.

It wasn't an easy paper, it wasn't particularly hard. It had some tricky questions, but tricky questions are more standard on the recent papers. If you found it hard I would advise that you go through all of the Solomon papers as well as the recent Edexcel papers.

I would be very surprised if it was below 60 for 80ums as the last two boundaries were 63 and 64 and they were not easy papers (from what I can remember).

so 62-64 would be reasonable to assume for 80ums. 100ums will almost certainly be 75/75.

you are a gangstaaa, i love you

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.

There will just be an answer mark for 7a) right? My working was dodgy but I still got the answer

What do you reckon 71-73 would be? Also, how many marks would I drop on question 2 for getting the same factorised form as you, but writing the solutions as x=4 and 1/2 and then getting the y coordinates wrong also because of it?

Thanks Arsey! For question with the inequality in p I got it correct but with x instead of p would I lose a mark for this? Also what do you expect the grade boundary to be for 100 ums?

Borderline c and B I would say

Will 65 be an a?

For Q6, I got my dy/dx as x - 3/2 - 6. How many marks would i lose for that out of 5? And also how many would i lose for part b as i needed dy/dx to work out the equation of the line.
