NMR at year 12 is easy. NMR after year 12 = death.
NMR in CHM1011 (first semester monash uni chem) is pretty similar to year 12 - just more complicated molecules you have to identify & draw, not very hard !
Hey, i'm doing CHM1011 (for uni enhancement), what is it like compared to Chem 3/4? What about CHM1022?
So much harder, Chemstry in VCE is very easy in comparison, its just about basic understanding and then perfecting. Uni chem is far harder, and its all about understanding, and then moving on - you barley have to do any practice because if you understand you will do well. CHM1011 is actually fine its basically an extension of everything you do in Chemstry with heaps more added in and very very crammable - we pretty much all got HD averages.
CHM1022 is quite different, i cant tell you honestly in comparison since i didnt exactly do anything or study for exam. Im sure its the same crammability (

) as CHM1011, but not as easy content.
