Pure quality.... did well in my chem gcse but thats probably what i'd resort to now

((got the awful feeling thats how i did one or two of my less comprehensible uni exam questions, and maybe part of my honours project - too afraid to read back through it.... passed it though, such is the state of our educational system))
Thing is for the first couple of questions, they're all valid answers, within the letter of the question, even if not the spirit. Shoulda got some marks for it (hey, what are those diagonal lines if not tick marks?)
love question 3

where'd it come from - it's really your own??
