    I don't know man- it seemed easier in content-wise than the other past papers but i know from experience you can easily miss marks from not mentioning a key term or something so my prediction is that i probably lost about 20 or so marks

    Gosh is there any chance the grade boundaries would be low this year???!


    Btw for the alkene with no e/z isomer, would i get a mark for drawing but-1-ene as it has 3 hydrogen's attached to carbons and one ch2ch3
