Ok, i found my PS:
"Biochemistry fascinates me..."
no, it doesnt.
"...I have greatly enjoyed the biochemistry and genetics I have
studied at school"
no, i didnt.
"... I have
found that the more I learn, the more engrossing it becomes"
lie
"I am looking forward to contributing
to both the academic and the wider aspects of university life"
...whichi have failed to do so far in any sense at all.
cambridge should introduce polygraPHS.
on a different note - I am now a fire warden! Is that a frying pan I see?!
