OCR PHYSICS B G494~ 11th June 2015 AM ~ A2 Physics

no probs how are you finding physics? i struggle with the key terms and the 3/4 mark questions are the worst..

Does anyone know what the average grade boundaries are so I can grade my past papers?
Or is there a website that shows them all for each year?

Be warned, i think OCR are out to ruin our lives

lol you only just realised? We all saw the horror show that was G491 last year right?

There's a reason why OCR B physics' grade boundaries tend to be much lower than other exam boards. I've yet to see a paper where it is 90% for an A* (i.e. it was a nice paper) for OCR B physics (yet there are plenty for WJEC chemistry), but I've seen a few where it's 75% for an A*.

Yupp, grade boundaries are usually quite lenient on this one, but just had Chem F324, geeeezzz... They really are stepping up the game and I think they'll make it exceptionally hard after all the complaints we gave them last year, just out of spite

btw anyone who's done last summer's G494 - the question that states "kinetic energy remains constant/doesn't change" surely they mean that "total energy" doesn't change.

Given that in the markscheme, kinetic energy bloody changes.

Is this the asteroid questions? I did it as a mock and it threw me, and after looking back at it, I think it means the total energy doesn't change (ie: remains constant), but GPE can decrease (or increase) and so KE changes to ensure the total energy remains constant.

Kind of put revision off for this since forever and have only started today, then got bored after 2 past papers.

You can thank me for the low grade boundaries

Read the question carefully, it caught me out the first time around also. It's saying that no kinetic energy is lost during the collision, not during the change in orbit.

Anyone else worried about what they'll throw at us this year after the awful G491 last year and today's OCR chemistry? ;p
