hey, im a first year at leeds doing chemical engineering and coincidentially enough wanted to do dentistry before hand (got a condtional offer but just missed my grade requirements for it).
I can't really give any advice on it since I got in through clearing with a dentistry personal statement, so I'm not even sure of what there requirements for this course are. But any work experience in the process industry - where items are manufactured, processed etc or just generally in the chemistry industry/general fields of engineering will always make you stand out, good thing to talk about in interviews etc etc
