oh my god!!!!! :frown:

is anyone else majorly stressing about this exam? Out of all my exams i was best prepared for chemistry which i need an A in so i tried really hard for that at the expense of physics.. had the exam yesterday was a ridiculous paper and have definitely screwed up! Also need an A in physics and i now feel like there is no hope :frown:

arrhhhhhhh someone please help me with some physics?! I despise this board!!!!!!!!

Can anyone explain the logic behind G495 being before G494?!

OCR and logic rarely appear in the same sentence. Actually the only time they do appear in the same sentence, is when someone's discussing how illogical the course and board are.

Could of had a week free to prepare solely for G495, but now thanks to OCR I have this the day after Maths C4 and a week to prepare for an exam paper shorter than a trip to the toilet :angry:

Do some past papers, including the legacy papers. They are very helpful.

ok, i feel like it has nothing to do with the stuff in the revision guide /stuff weve been taught over 2 years :frown:

Also is this paper synoptic like chemistry etc is its the last unit?

Also, i know this is asking a bit much but is there anyway you could explain the electrical side of things for me, motors etc in specific?

And if you (or anyone else) have questions post it up and i'll try answering them (im not completely stupid, did get an A last year :tongue:

just majorly stressed right now! ) as i think this would be a good way of revising!! :smile:

Oh god! Good luck to you too! I'm almost regretting applying to places that need A's in Physics, because its gonna be difficult to achieve! :tongue:

"suggest how an electric field helps to ionise gas" anyone? i thought this was quite hard, i hate wordy questions!!

What is physics B, from what I can make out it's like physics A but with some sort of article stuck in it? :s-smilie:

STUPID COURSE! (incase you are thinking of taking up a level physics - do not go for this course if you have a choice, you'll regret it like most us! )

An electric field produces a force (because virtual photons are the force carriers.) This electric field produces a force in the opposite direction to the field. If the electric force is stronger than the electrostatic force, that is bounding a particular electron to the nucleus, the electron will be emitted. A loss of an electron is ionisation.

That's how I would write it, at least.

I did the same exam as you I think - I didn't want to know what everyone else though of it 'cause I wasn't too pleased either but I gather that the rest of my year found it tough too so hopefully the grade boundaries will be kind!
I'm in the same position as you - I need all A's but all we can do is stay calm, use the specification thing as law and get as much practice as we can! Try not to panic and don't give up! ^_^

oh right, well I'm already doing A2 OCR Physics A anyway, just came on this thread to see what Physics B was about, because our school only does Physics A.

Personally I find some of the questions an absolute b**** but at the same time like the challenge, it's just under the pressure of the exam you don't always get time to think about the question, you often have to just dive in :frown:
