I began leveling in CDIS after I received my initial Bachelor's in another field. I did that for one semester before applying for a 2nd Bachelor's since the same classes are required either way, might as well have something to show for it in the end. I just graduated in May and will begin the CDIS Graduate Program in August. I thought Neuroscience was the hardest undergrad course I took but I still got all A's taking 16+ credit hours each semester. If you listen to all the lectures and ask questions, that helps. It is helpful to look up rateaprof.com and read reviews before choosing a professor, if you have an opportunity to choose. Mr. Wilkerson and Dr. Swift are the most responsive, in my experience. Mr. Martin, Dr. Hall and Dr. Lingnau are great as well. Weems is tough, but gives extra credit.
