Does anyone know where I can find an unofficial mark scheme, even for other CIE exams in general?
found this one quite easy compared to the specimen paper, lots of people seemed to have had lots of trouble with the last question about esters and polymerisation. for the ester I got methyl ethanoate. and wtf was the catalyst??

I found the multiple choice quite difficult, the extended theory was average at best. Does anyone know the percentage for an A* usually? Overall, an average year, perhaps a little difficult. I said Nickel, but I think it was sulphuric acid.

The catalyst was a strong acid, any strong acid should be correct

I said sulphuric acid for that. I'm so happy about paper 4, but paper 2 was terrible!!!
