Yeh, you got that right, the format was totally different and there were 2 mole questions. The one with the concentration and the one in which you were supposed to prove the metals thing. The last question, the polymer was COOH- and NH2.
I hope thats correct.

I think that the threshold for this term for IGCSE CEMISTRY PAPER 31 will be very low. Just like the previous year threshold.
Atleast i hope so. :D

It was photosynthesis because Photo chemical was already written in the statement.
The next one was cell.
