Can anyone tell me if this is an extremely rigorous course schedule?

<p><a href=“Department of Informatics < University of California Irvine”>http://catalogue.uci.edu/donaldbrenschoolofinformationandcomputersciences/departmentofinformatics/&lt;/a&gt;&lt;/p&gt;

<p>I was wondering if these courses require a good knowledge of calculus or does it just have to do with learning skills in soft engineering,computer programming etc.</p>
