M1 Jan 2016 IAL Model Answers (Edexcel)

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.

Thanks. Looks like I got 74/75. Oh well. I hope that's still full UMS. I reckon Q2 would trip a few people up as well as the co-ordinates of Q4(c).

Did the PDF site I give you come in useful? :smile:

I would guess 64-65 for an A. Though it could possibly be higher. Last year some UK papers had 67 for an A as the boundary.

Where's the paper? >_>

Urgh, and I thought I'd got 75/75. I'm just an arrogant prick. Serves me right. :tongue:

Probably 98-99 UMS I reckon. Still excellent. Where did you lose the mark? Q2?

And yes I used the compressor but I think it's better off just sharing googledoc files as you said, it's much easier

The paper is there too... Click the googledocs link it's more readable

Nah, missed the time-coordinate of max-velocity from A to max in the sketch. I did from O to max instead. Got 14/g.

Great. Glad that helped. Googledocs is v.easy. What about the merging individual files together?

In Q.4 Would I lose the marks for the whole question if I calculated the parts based on 11.2 being the initial speed ?

Probably lost like 8 marks out of complete foolishness. Reckon I'd still get an A?
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?

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

Don't need to do that anymore since I've found a brilliant app which allows me to scan via my phone and put them all in one document. Thanks though :biggrin:

Camscanner is great, I use it myself. Glad you're catching up with the times. :wink:

Argh, that's a pity. I was going for full UMS. Oh well. Hopefully Q2 will have proven challenging for enough people.

Don't lose hope. C3 had quite a lot of 74-75ers for full and this summer we all thought that wouldn't change. But it went down to 71 somehow.

Grade boundaries are weird. I didn't do the paper so take this with a pinch of salt, but I think you might well still have full
