I have decided I really really really want to go back to school to expand my education into environmental engineering. I currently have a BS in Business Admin from UC Berkeley. I have researched several masters programs, and it is looking like it will be very difficult for me to even get into a program w/o any hard science/math background. I would like your opinion/advice, on whether it is a good idea for me to go back for a BS in environmental engineering. One (really the only) concern is financing another BS, since I won't qualify for federal financial aid. I currently have a very low paying part-time job. Fortunately I do not have too much student loan debt since I transferred into UC Berkeley (in-state student) from a community college. *Just some background: Before majoring in business I was going to study chemistry (I loved science and math in HS/Freshman year college), but after being told the lab was a very lonely place, I switched. I recently started a company which required me to relearn some basic chemistry, and I realized how much I loved science and dislike business. After the company failed (unfortunately shortly after it started), I audited several different science classes and spoke to many professors/professionals. This is when I discovered how much interest I had in environmental engineering. After researching more into it, I know this is really what I want to do; just trying to figure out how now.
