it was fine

A bit annoyed as I misread the six mark question and talked about gases instead of petrol

Preety good but silly mistakes will bring my marks low

which question was that

the six marker where you had to compare the properties and uses of petrol and bitumen

are you sure that was in the 1C paper and not the C1?

Wasnt it 3 marks?

Yeah i got that

The bitumen question was a 3 marker

I made 3 silly mistakes on the test: I idiotically wrote down 12 instead of 120 by writing down the wrong; I wrote (1,1) dibromoethane instead of 1,2 and I wrote Mg2+ instead of O2- or whatever. Apart from that, I think I did alright. Also, what did you guys say a monomer was? I said it formed part of a polymer. I also drew a double bond on chloroethene question and a repeating unit for the question before.

On the second last page was it low and low again?

I believe it was low pressure (right hand side has more moles of gas, so system opposes the change and favours forward reaction)
and high temperature (forward reaction is endothermic, as denoted by the positive enthalpy change)

What order did you put simple molecular giant covalent giant metallic and giant ionic?
