Anyway xianglaoi or whatever your username is cos idec it is they're.
Also how many igcses or gcses for that matter did you do in year 10? How does your cv compared to mine ATM? Exactly
I did one gcse in Year 10 - but I also came in the Top 50 people in the country in a Sixth Form maths competition in year 10. I think that's gonna look better on my CV than an A* in maths...
To be fair, you sound like one of the most intelligent people in the world, so I wish I had have done four gcses last year

Yeah, same as me then. I don't really see what else you could have put as hydrogen fuel cells only made up a very small part of the course.

What did you put for why is silver resins used in a home filter?
I put silver is antibacterial

No the answer was so obvious it was Phosphoric acid .. They gave u a clue "acid" and the pH for acid less than 7

I said 'it helps to stop the bacteria from contaminating the water, then I put that it was an anti fungal' don't think I would get the mark

For that question, I said it doesn't produce Co2 emissions, which stops the greenhouse effect and then for the second reason I put that it conserves fossil fuels, not sure if the second one is correct though.
Yeah you'd get a mark for that, as you're suggesting a different form of energy. I wrote something similar to it.

Silver is used to prevent the growth of Bacteria and also kills them.

I found the C2 exam pretty easy. There were sections of maths, which were pretty simple and most of the questions were basically the properties of substances like metals and compounds

I'm aiming quite high for this exam and I thought it was easier than B2 :facepalm:
What are your opinions?

The gas chromotography question was 2 marks, you had to say that if you drew a pen line, and it accidently dissolved in the solution, it will make a mess and will ruin the experiment because you wouldn't see the spots properly.

I got Heat Energy for the Hydrogen Fuel Cell one.... Many people in my school did as well :O It was a 50/50 split between Electrical energy and Heat energy in my school.
But isn't the purpose of a hydrogen fuel cell to produce electrity, heat energy is just a by product idk
