iGCSE EDEXCEL PHYSICS DISCUSSION 2012

there was a lot of debate afterwards about the left hand rule question, which way was the current flowing?was the answer left or right for motion?

the wire moved to the right and you dont even need the rule for that as the wires were all bunched up on the left which acts as a kind of spring in my head hehe

Damn easy paper.......but ambiguous...what about the last question...?

For the penetrating powers of alpha and beta...what were they expecting?

The last question, if that was the one about the 2 cans being knocked over and him saying the travel at the same speed, I said no as you need a bigger force/speed of the cloth to get two cans to move at the same speed as the first, and he said he threw it at the same speed....I think I put something on those lines...

It was showing 3 time periods so the frequency was 1/0.002 or whatever so the answer was 500Hz. What do people think the grade boundaries will be?

Hopefully 140/180 as a sharp maximum. The second exam didn't go that well.

I really messed both physics papers up
What do people think the boundaries will be?

That high? I didn't find it hard but I thought it was, on the whole, on par with the january papers in terms of relative difficulty. I reckon I got around 160-165/180 so hopefully I'll be fine. What do you think the lower bound will be for the A* boundary?

Surely not the January 2012? I thought it was around the same as the June 2011.

I'm always incredibly pessimistic in my self-marking, so I wouldn't know. If it sticks to 140/180 then I can be fairly certain of an A* (although I might have got 170/180 or even slightly higher - probably not) . I wouldn't like to guess a lower bound.

Haha fair enough , I reckon I got around about 113-115/120 in paper one and ~56-57/60 in paper 2 because of that stupid radiation question I talked about the ionizing force, the rate and frequency of absorption, what materials they pass through and nothing else . How many marks do you think I would get for that?

i reckon 3 or 4? sounds good enough

Lol guys come on, it doesn't matter. That's obviously an a*

but these papers were dodgy compared to past papers

yeah so thats why im saying dont worry as grade boundaries will be lower
