There are many handouts that are helpful for planning your academic career in chemical engineering at Michigan Tech. Printouts are available at the Advising Center on the second floor of Chem Sci (across from the elevator). All handouts are also available on the web in PDF form on the Advising Handouts page.
The first year of graduate school in chemical engineering typically involves taking advanced courses in transport, thermodynamics, kinetics, and mathematics (partial differential equations). It may also involve specialty courses specific to your area of chosen specialization. Anything that makes those required courses easier is a good idea. I feel that at Michigan Tech we do not go far enough in transport, so I recommend that you take the graduate transport class (CM5300 Advanced Transport Phenomena I, 3 credits, Spring, prereq=CM5100) or Polymer Rheology (CM4650, 3 credits), either of which will introduce you to the use of tensors in mathematical analysis. After that I recommend taking our graduate math class (CM5100 Applied Mathematics for Chemical Engineers I, 3 credits, Fall) or any advanced mathematics course that interests you (some examples might be MA
