p123: 36
p456: 34
30-34 for p123
Wasn't last year june a really hard paper :eek: i think it'll go up a bit then because this has been the easiest (yet not easy additional physics), I'd say 38

You?

I think that P123 will be about 32 and P456 38 too. That June 2013 wasn't that difficult, just some annoying questions.

Do we need to know how simple optical telescopes work? The specification says that you need to know:

Objective lens - collects the observed light and forms the image
Eyepiece - magnifies the image so that you can see it
(and refers to powers)

(I'm probably misreading the specification here)...

Do it for science!
You don't wqnt to be stressing during your holiday over the physics exam and kixckin yourself for not trying!
It's only physics xD

If it were chemistry or biology it would be a different story, but I'm not taking physics at A level so..meh

Still gotta learn all those gas laws..
hurray

Pleased that I helped! Any other C7 (or P7) questions let me know - it's good revision for me too!

Yeah my teacher wasn't that good, so a lot of my C7 is self-taught too.

The 'in context' papers are the old spec ones, but as I said you can just ignore question 1 since that was the question that relied on having the source sheet and complete the rest of the paper because it is still relevant to C7.

I posted a link in one of my earlier posts in this thread to where I uploaded the 2008, 09, 10 and 11 summer papers and mark schemes for C7 in another thread.

Sadly A173/02 has only been sat once and OCR hasn't publically released this paper. Your teacher may still have it - I got the B7 June 2013 paper from my biology teacher and my physics teacher emailed me the markscheme for that B7 June 2013 paper AND also sent me the P7 2013 paper and markscheme - so if anybody wants that let me know and I will share!

The closest thing you can get to what we'll be sitting tomorrow is the specimen paper which I think is quite a hard paper.
Hi, do you have the p7 2013 exam and mark scheme that you could share with me? Thanks in advance

Does anyone have any predictions as to what will come up on p7?
I did really bad in p1-3 (hopefully a* is less than 30) I did okay in p4-6 and I got 60/64 in coursework so I really need to ace this exam if i want that a*
Here are some questions if theyre of any help

Observing the sky

1. Explain why the moon takes 25 hours to rise each day
2. Explain why stars take only 23 hrs 56 mins to rise each day (hint 360)
3. Explain why the sun takes 24 hours to rise each day (spin axis)
4. Explain why the planets make complicated patterns in the night sky
5. Explain the phases of the moon (hint diagram)
6. Explain eclipses and why they are so infrequent (hint-its not lilt)
7. Explain how angles can be used to find astronomical objects (hint sphere)
8. Explain why a sidereal day is 4 mins less than a solar day (hint-360)
9. Explain why different constellations are visible at different times of the year
Telescopes
10. Explain why eyepiece lens has to be more powerful than the objective
11. Explain how concave mirrors bring light to a focus (hint diagram)
12. Explain how parallax helps find distance to near by stars
13. Explain how a smaller parallax angle means the star is further away
14. Explain why Radio telescopes are so much larger than optical telescopes
Scale of the universe
15. Explain how what factors affect how bright a star appears to be
16. Explain how Cephied variable stars help astronomers find distances to stars
17. Explain how Hubble used Cepheid variable stars to put scale to the universe
Gases and stars
18. Explain the formation of a Protostar in terms of collapsing gas cloud
19. Describe the forces on protons in a nucleus
20. Explain our stars life cycle
21. Explain the life cycle of a star several times larger than our own

What subjects are people taking in a level
Im still in year 10 only doing physics this year, but is as/a level maths hard?
I do sometimes sturggle with gcse maths though lol
Anyone taking chemistry, economics or pyscology? I also heard english language is really easy

"Is Alevel maths hard".
Yes, yes it is XD
I'm taking French, Biology, Chemistry, Physics, General Studies and Level 3 Extended Project 'Alevel'. (They force us to do general studied and EPA at Notre Dame. :/)
