Prof. Wallis knows his stuff and presents it fabulously. Wallis is concise, witty, and knowledgeable, and his lectures are always a pleasure. Prof. is the best I've had. There seems to be a genuine concern for the students. Availability of lecture slides a plus.
Web resource is invaluable and renders much flexibility.
The instructor, prof. Wallis provides more assistance and sources of information than any of my past or present professors. His website, providing access to his lecture slides and giving links to other sites of interest has been a help. Enjoyable and interesting. Innovative lecture style and presentation tools.
