Hi, these are my model answers to the M1 IAL paper.
Very easy paper.
Maybe 2(a) might cause confusion.
4(c) might have been misread and answered poorly
Expect high boundaries. Last year quite a few UK papers had 67 for an A as the boundary, I wouldn't be surprised if it were 66-67 for an A for this paper.
ahhhhhh....in the last question , I wrote down T - g/2 = 2ga instead of T - g/2 = 2a....I knew the method to calculate the latter parts, how many marks would i lose in this question in total....?
For the last question, I used cos(a) instead of sin (a) in part b. The rest of my answers are wrong because of that but my methods are correct. How many marks do I lose in the whole question?
Probably lost like 8 marks out of complete foolishness. Reckon I'd still get an A?
Should be at least an A yes. I think it's quite possible that the boundary could be 66-67 for A, since it was a relatively straightforward paper and IAL students tend to perform well. In this case you'd be just scraping it.

I'm not sure about how much marks lost etc, but here's the man who could help @TeeEm
