Does anyone have any idea if you can write your answers in standard form on the physics exam? For example if I worked out an equation like 1/2x1200x5000^2 and the answer was 1.5x10^10J could I leave it at that, or is converting the answer to an ordinary number required?

What did people put for the six marker on the unit 3????!! it wasnt what i was expecting
just how you carry out calorimetry basically: weighing the fuel and water and temperature before the experiment, heating the water and then weighing them again. i also added a couple of lines on repeating the experiment and taking average readings in the hope that it would get me a mark or two~
Dying for A* overall but ****ed up so bad.. Like I need the boundaries to be like 39 for A*... Please !
I have the same problem, but I messed up chemistry instead. :/ Like, I overcomplicated the questions so much...it annoyed me because I know for a fact I can get A*s, I just messed up on the day.
Maybe you'll get enough method marks for an A*. Even if you don't get it "right" but still put relevant info (like on the higher) markers, they'll probably award marks. We'll just have to see on the day. Also, we have core to go yet! (well, I do.) you could well average an A*, especially if you have a good ISA grade.
Well if you talk about the wrong structure in a substance (like diamond) then they usually allow 1 mark for it, so I'm praying they allow me one for saying hydrogen haha. Oh god yes I know how awful was the biology paper, I felt so screwed over by aqa, it hardly involved any actual 'science'
Guys please what was the question about distillation - advantage or disadvantage?
It was just generally that distillation is expensive- I suppose that you would both go into how the process how the process has many steps and also that large amounts of water would need to be distilled- using a lot of energy.
