the exmas on thursday.. anyone else feel like they are going to fail it?

I've done my forces and motion in jan and did ok on that but waves and electron/photons..

I feel like I'm going to fail them.. I don't understand most of the electricity espescially the photons and the interference of waves is like what?

And i have been revising/doing papers but can't seem to get higher than 60% on them!

I'm dropping this next year... so does it really matter if I don't do that well in it? Do good unis (durham, newcastle, UCL...) actully look at that?

[soul02]

i think unis will look at it
its better to try and do well in all your subjects x

[rdu11]

yer i no it is..
My mind just can't seem to click with physics.. doesn't matter how hard i try!
oh well..

Im doin this 2. i did photons/electrons in jan and got an A, but got waves and forces and motions this time

waves is quite simple, and forces and motions is comin along nicely but is prob the hardest out of all AS physics

I think you'll notice that more than the other two modules,'Properties of Waves', is, for the majority of the time, rote based. It just requires you to learn many definitions and experiments. In that respect it is similar to Biology on the whole. There are limited equations for the module, just the equations for power (P = I / 4*pi*r^2), angles of refraction, and the critical angle (n = 1 / sin C). The most difficult thing, arguably, about the module is the use of the equation (lambda = WS / D) or whatever interchangeable letters you use, to determine fringe separation etc.

What should be mentioned however, is that if you find wave properties a difficult module, it is only worth 20% of the AS level. It is added to your coursework, so, pending on whether your coursework was of a good standard, you can easily get away with a relatively low mark come next Thursday. Forces & Motion as well as Electrons & Photons are each worth 30%.

I'm doing all three modules on Thursday, the forces module is the hardest. The wave properties module is about learning experiments, which is hardwork, really concerned about these exams, good luck to everyone.

I generally find physics quite easy, I didn't revise a lot and i got 79/90 for electrons and photons.

For electrons and photons, there is not way of getting a good result without knowing the photoelectrics effect. You need to know basics like Q = IT lol and V = IR LOL, but there is always like a 10+ marker question on it and i bet that's where you're looking marks. You need to know terms like the threshold frequency and the definition by heart.

For waves, the marks are spread out. But mostly are concentrated in interference and refraction. People often lose marks here because they forget to put arrows etc...But practise makes perfect. Out of all of them, he same questions always come up for waves, the only variable is optic fibres which doesn' come up that much of the time.

Anyway, past papers make perfect, remember the markscheme and literally remember how to answer the paper after you've seen the mark scheme because when you get the real paper, it'll be like you've seen the mark scheme for that one because they a generally indentical. Good Luck!!

cheers 4 de advice dealerG but i think if anyone needs advice they should come to the man who got

88/90!!!
in electrons and photons
