I'm pretty confident, I just don't think my life will ever be the same when preparing for exams after this years C1, otherwise I would say very confident

Can some people help with the mark scheme, I didn't get chance to save my answers in the calculator today.

I am not sure I understand the whole 'unofficial' mark scheme, how do you know you got the correct answers? Are you even qualified to do this

Angle between two 4N forces was 82.8

It should be greater than 90

Teachers often pitch in, so yes qualified. We also know that we have the right answers because people tell you otherwise and we show the working on the document.

How did you get 82.8?

How did people get 82.8 degrees for the angle between the 4 newton forces? I got 97.2 by using the cosine rule, a^2 = b^2 + c^2 - 2bccosA and solving for A

Give me a couple minutes. I'll redo the question and post the method in the MS
