Im a current Chemical Engineering Masters student.
Which one would have higher graduate : employability ratio (any sources plz) and which course would be recomended to which type of person?
No idea
Any extra reading you would recomended for either of those subjects?'
Chemical Engineering - None. Seriously, don't bother.
Average starting salaries?
Chemical engineering has the highest starting salary from all the engineering disciplines. FTSE 100 companies GSK, Unilever, BP, Exxon, Shell etc all heavily depend on Chemical Engineers for their profitability. (Oil extraction, colloid creation, drug delivery systems etc)
What does the study involve for both of these?
Maths is essential for Chemical Engineering. Some universities require Chemistry in addition, Either option is okay. I have done modules that require physics and some that require biology. Great thing about Chemical engineering is that is it so diverse!
