Does anyone have any predictions on grade boundaries?

Posted from TSR Mobile
I think it is usually mid 70s for an A

EDIT: These are what the usually are: 70/100 for an A, low 60s for a B, around 55 for a C
4. I think section A was pretty nice, section C was as expected and B was fairly tough.
by far my hardest question was sec c 12, calculating that g was 2.8? I think I've fudged that one ><
also, sec B question 7) b. how did you get the g value of 140? I got 116 and that seems too low to be an 'almost'
Any ideas?
5. Argh! Was a nice paper, but just realised that I put the sensitivities of A and B in the wrong order!

Can you remind me what question 7 was again?

what did people draw for the velocity/time graph
I think it was an S shape graph (increasing gradient moving into a reducing gradient). At the point when the force was at its greatest the v/t gradient is at its steepest. The gradient then reduces to zero by the time it gets to the point when there is no force on the ball. After the ball has left the foot I put a slight deceleration. Not absolutely sure that this is right?

Have a look at the mark scheme thread

The value in the question was weight and you needed to divide by g to get the mass and work from there

Think I did that? Maybe I was a bit mean reading off the graph :s
10. I thought the exam was alright.

I didn't revise, so I'll probably get a B.

Should be interesting.

I also forgot to plot 1 of the 3 points we were meant to plot on the graph, just noticed it as the invigilator was collecting the papers.
11. what value did people get for the gradient after drawing the line of best fit?

that insert we got in the exam

you could view it before hand and prep for section C using it

Oh right! The pre-release article. I didn't actually need it in the exam.

what did people draw for the velocity/time graph
I drew like a curvy sigmoid shape until 0.05s and then just let the speed stay constant at 35ms^-1? Did I do it wrong?
16. HELP! I plotted a point slightly off, and my gradient was wrong; Will I get ECF for the questions after that?

I got 2.7. It's right because using that value, gave me g of 9.89 which is pretty accurate. But there will be range. I'm guessing 2 to 3?
18. For the last question in Section C, did you guys get 2.94 x 10^8 and uncertainty 0.3 x 10^8. Uncertainty has to be 1 sf.

What was your gradient. Mine was 2.7 which is in the right range. The right answer will probably be allowed anything from 2 to 3.
20. This is the most dry thread ever. Just goes to show how much we're unlucky to be doing this ridiculous physics board.
