logically, for the synoptic parts they arnt guna ask hardly nefing from C1 as its too easy!! or C4, there will be some as its hard but they will assume most people will have just take it so will know it pretty well so there shouldnt be too m uch in it. i think its gota be C2 and C3 we should concentrate on!
i got C4 retake today-eeek! i suk at spectroscopy but i got an ok grade last time so its not the end of the world, jus helps with synoptic.
if people are worried bout C5, ive done my notes on them all and its not as bad as it first seems. there are only a few key ideas to know- cell potentials, gibbs and entropy, how shell splits=colour, catalysts arnt too bad. but u must concentrate of the colours and the variable colours you get with some when you add zinc and hcl!
there, thats it!
