All right, my emphasis in Civil Engineering is in Environmental Engineering. Also did a couple semesters in General Chemistry, Organic Chem (and lab), Inorganic Chem (and lab), Instrumental Analytical Methods (and lab) and Physical Chemistry. Stayed away from biology, too cellular for me, and DNA whoa! Still want to do more environmental engineering classes. Like aquatic chemistry, Unit Processes-Chemical and Physical, and Contaminant Hydrology. Just finished Energy and the Environment this last semester. Strange communicating with a smart education woman other than at the university. Biology, I could not do it. Your one smart woman. You obviously still have your short term memory, to have done biology. Organic chemistry taxed my short term memory more than any of my Civil Engineering or Math classes. Now as long as my funding agencies hold out and I can continue to work and go to school. Of course if I take all I want it will take two more years instead of one! A PhD, great for you Biffer! It is taking me a lot later in life to get my degrees. Had to receive six years of Army education as a medic , and the experience of three marriages, lots of illicit substances, and subsequently getting clean and sober, to smarten up enough to go back to school. Once again Biffer, keep mit up your doing Great!
