So I have a BS in Chemistry and a BS in mathematics and just have been recently laid off from my job as a chemist at a pharmaceutical company. I have been thinking about going back to graduate school for ChemE. It seems right up my alley. The only thing is that I really don't want to have to go back and take out more student loans to take undergrad ChemE courses if I don't have to. Graduate school for ChemE should be free like it is for all the sciences right? If I were to go back to school for ChemE could anyone please fill me in as to how many and what undergrad courses I would have to take move into ChemE?
