Section B question 5, calculatio part, does the question mention the string is horizontal?


Yeah it did say horizontal circle :smile:

The very last one didn't know it was mechanical strength I said it was so the current went into the sheath, I don't think I had seen a question like it.


Ah I said power losses :/ stupid mark lost. I don't know why I didn't say strength :/

Haha thanks! It's funny how many repeated questions were in that paper.

Questions 3, 5, 6, 10, 11, 15, 18 and 20 had all come up in a very similar form, if not the exact same before on past papers!

Can anyone link me to an unofficial mark scheme?

Haha. I got the last one wrong unfortunately. I said the steel was for minimising power losses :/

Possibly 60-61. The multiple choice was easier than last year but the written was slightly harder in my opinion. It might balance out to give the same sort of boundaries :s-smilie:

I agree, the multiple choice seemed slightly easier than last year's! Although there were a few questions which might have caught people out, like the 4R one and the couple question (considering couples aren't in the A2 part of the spec).

I can't see the grade boundaries going up to be honest, I think that they will remain around 60 for the A* mark or maybe even go down 1 or 2 due to AQA's mistake.

24/25 is amazing! I know for sure I lost atleast 7 marks Even if you made silly mistakes on section B you'll still come out with top marks

Can someone explain 2ciii) to me please? I got a value of 1690Vm^-1, using the equation for a radial field. The field in question is definitely radial, so I don't understand why people who have got the 1560Vm^-1 value have got that using field strength for a uniform field?

What value for Q did you use?
would 50 be ever a B in this exam (grade boundary)?
I think I messed up the MC pretty bad.. Got about 15/25 :frown:, so overall what would 50/75 be?

If you look at the past paper boundaries in the first post, the B grade boundary has always been below 50, and it's unlikely to move enough to change that this year, so it should be :smile:
Hi guys. Will 65/75 be an A*? Thank you. I don't really know how hard this paper is compared to the past papers. What do you reckon?
