I work for an oil company. I'm a licensed civil engineer, graduated chemical though. I found chemical engineering to be more physics based (momentum, shear, statistics thermodynamics)
The classes were tough (average 40% on midterms/finals), a lot of the math I had never seen or used before (I received all As in my math and chemistry class - sans biochem, premeds really mess up the curve with previous tests).
I never learned about Euler's cut principle / tensor till my second class of BSL (Bird, Stewart, Lightfoot, infamous ChemE book). Had to learn both BSL and tensors in addition to a tight class load. You definitely need time management. http://www.ekayasolutions.com/ech256...alanceLaws.pdf
ChemE is more physics based than chemistry based. I took civil classes on the side (hence the Civil PE) - 3.89 Civil GPA, can't say the same for my ChemE GPA.
Your mileage may vary as I went to a theoretical school / graduate school emphasis versus a practical school / industry focused.
