# OCR B (Advancing Physics) Field + Particle Pictures exam today watch

1. (Original post by johnwarneruk)
i got 2n u sure that was wrong?
I reasoned that 2N on something with a mass that tiny would produce an acceleration way too huge to be true . Speed of light in nanoseconds, but then that'd start getting relativistic so maybe we are right with 2N. Good to know it wasn't just me who got that though.
2. cant remember thats question that paper was sooo hard lol. did any u gus use the equation F=QE. all of the show me questions were not bad was that forc on a particle question where u got 2N a show me 1?

what mak out of 70 do u rekon is a B?
3. 40 B or something? depends on UMS and your coursework Grade for that module

wots the csewk 2 exam ratio?>
5. 30% ish.

Basically, each module is out of 119 and 127 RAW I cant remember which is which, your coursework mark is then times by 1.215 or 1.4** something respectively, and added to your exam mark to give you a total, which then becomes UMS. between 90-95 Marks for 127 is usually A i belive dunno about 119.

Next time i go downstairs ill find a markscheme and find out.

Each of the 2 pieces of coursework this year is worth 45 UMS. So out of the A2 papers it's 30%. The 3 last year were worth 30 UMS each, so overall it's 180 UMS or 30% of the whole of the A-Level.
7. course work is worth 40% of the exam im sure of it. our teacher is always saying!
i thought a B is 50 out of 70 not 40? cos 40 sounds low. i havent even got 40 i rekon cos that exam was hardcore physics lol solid
8. Well.... it seriously depends on your CW mark, it's about 40 for a B if you got 35/40 in your coursework im working on...
9. Exam is out of 90.

Multiply this by 0.7 to get 49, which should roughly be a B.

According to my teacher grade boundaries are always slightly lower because more people mess up Physics. So you're looking at around 45-49. (I say 45 because I thought the paper we just did was relatively harder than some of the others I've done, and because most people on here are complaining about it as well)

So for the 2nd year what are the actual UMS marks?

I know Clockwork Universe is out of 100. So that leaves 200 marks shared between Field and Particle Pictures and the Synoptic, anyone?

Yeah, the synoptic is 90 and the FPP is 110. That's UMS btw. The UMS marks for each of the papers today include the associated coursework.

page (vi) of this gives the breakdown:

11. I'm so scared about the synoptic paper. Especially the random questions!
12. cheers
13. hey so if i got 34 for my c/w what do i need on the paper to get a B
14. Apparently there was a mistake in the FPP paper. The "show that" question after that one where they gave you the atomic mass unit (u). I didnt see it myself, so consequently i dont remember the question (i just know i got it wrong) but i hear the thing they asked u to "show that" was wrong!
15. meaning what? the marks will be awarded?
16. Im not sure. If there really is a mistake, im think they scrap the question, but it was only 1 or 2 marks anyway.
17. ok cool.
are the grade boundaries the same every year? or do they alter it according to how hard the students found the exam generally
18. nah i think i got the correct answer on the show me question about converting the mass in U to KG. it was somthing like whats the mass of X238 so u just x 238 by the number they gave u to convert u to kg.
u now the very 1st page where they asked u to calculate the force of the alpha particle nwhat equation was it F=qe or F= k x q1 x q2/r^2

and what do u guys rekon u need for a B

it was the inverse square law.
ok cool.
are the grade boundaries the same every year?
The grade boundaries are the same every year for UMS marks.
80/100 or 88/110 - A
70/100 or 77/110 - B
etc.
but they change the raw (or actual) marks you need for that many UMS marks.
