Chemistry

No argg... Damn... I screwed up my Chem. Iron sulphate is supposedly correct, unfortunately I put it in the wrong place. Screw up the whole QA question which was worth 9 marks. Damn. This just gets suckier... Higher paper was relatively ok, got tricked by the 1st ionization energy question though, thought there was some formula to it... Damn... damn... later get retained how... Haiz...
