I just when to the font page and thought about what I could relate to the question 
, you know the neutron emission question? I went to the back of the exam paper to look up the element 
I'm to dependant on that formula sheet
, you know the neutron emission question? I went to the back of the exam paper to look up the element I'm to dependant on that formula sheet Lol same!! I learnt how to use all the formulas anyway, but when I went into the exam the nerves got the better of me and I kept flicking back and front constantly

Momentum was relevant to mention as well as the fact that his driving forces was greater than the counter forces such as friction and drag. Kinetic energy would also be relevant, but GPE would only be relevant if you linked it to an increase in kinetic energy/speed. Also useful to mention that when Amir runs, he creates an interaction pair on the surface with a greater force that pushes him.
I linked G.P.E to his jump because he gained more G.P.E with a bigger run up and therefore more kinetic energy

Nah, it looks scary but the only proper equation is paralax and that is just some triangle chizz it's like advanced p4 and some stars 
I was so stressful for that exam though, I'm starting bio today because I ain't doing last minute like that again
fried my brain me thinks

I'm fairly confident for B7 & C7, it's just P7 that will inevitably drag my physics grade down further

I had no idea what to put for that one. Did you mention momentum, K.E, G.P.E & drag?

I mentioned momentum, velocity, force and change in momentum and the fact that the larger the momentum the harder it would be for him to stop. And then i said things about reaction forces and how his foot would be pushing down on the floor which would increase the reaction force. This would overcome gravity/weight and then make him jump. Although i spent the majority talking about the former

You made better points than me
I didn't mention forces at all

If the grade boundaries were 20 B 27 A and 34 A* last year, would the grade boundaries rise by a lot this year ? I want an overall A or something, but I failed this paper and got about maybe 26 or 27. What do you guys think this will be? Overall, how did most people find it at your school ? I hope this doesn't bring me down even more, I p123 was even worse for me !
The 6 markers were really kind! They were like 10 markers, especially the last one on radioactive waste, I write a page and a half on that!

These are what I put, can anyone give an approximate mark (or correct them! 
)
P4 6 maker:
At the start all of the forces are stationary (weight and gravity are constants)
When he runs, he begins to accelerate and build up momentum
Air resistance is not a greater force after a bit, his resultant force is to go forward (driving force) from the build up of forces
When continuing to run, he builds up more acceleration and momentum (work done)
This results in a greater K.E and when he jumps he transfers the energy to go higher/further
KE = work done, KE turns to GPE and then he begins to fall
P5:
Filament lamp wire is smaller so there are more collisions with the free moving ions
This results in a greater resistance and the temperature rises
This causes the filament lamp to glow
Connecting wires are bigger so there are less collisions with the free moving ions
This results in less resistance and the temperature isn't as great
This means that the wires don't glow
I think I put something else too (anyone got an idea?), but my answer filled the last line only.
P6:
I agree that there are risks as radioactive waste emits ionising radiation
Ionising radiation can kill/damage cells and cause mutations and cancer if people are close to the power station
However, power stations are built away from most people and disposed of correctly
Low level waste - (e.g medical gloves?
) - disposed on dumps/landfill sites - has a long half life, low activity - but public could still be affected
Intermediate level waste (e.g surgical equipment?) - disposed of by putting it in cement and steel contains - shorter half life, more activity - away from public as it's underground
High level waste (forgot to put an example...) - short half life, high activity - put in glass (vitrification), cooled to reduce heat and put underground in containers - away from people
Overall, there are risks but the benefits (no CO2, more energy) outweighs the risks of radioactive waste.

6- IF YOUR SPAG WAS ON POINT
on your last one, I ran out of time so so I didn't get to talk about the people side of the question as much as I'd like

Thank you very much! Yes I agree with your comment on the P5 question - I didn't see it in the spec/CGP book that it was a resistor too. The six markers were actually alright overall then!

I put instantaneous but apparently it's average. Average seems right too.

I kinda put tracers
How many marks will I lose if I put food, tracers & cancer?
