<p>What are the longest undergraduate course prerequisite chains, starting from freshmen entry without AP or other advanced standing (but also no need to take remedial courses like Math 32)?</p>
<p>E.g. the Physics major requires Math 1A -> Physics 7A -> 7B -> 7C -> 137A -> 111 (first 3 units) -> 111 (3 more units), which is a seven semester long prerequisite chain. Chinese and Japanese have optional courses (111, 112, and Japanese 163) at the end of an eight semester long prerequisite chain.</p>
<p>Are there any majors with a required course at the end of an eight semester long prerequisite chain?</p>
<p>Six semester long requisite chains are everywhere. I haven’t found any seven semester ones, let alone eight. I tried. You win.</p>
<p>Chemistry</p>
<p>{Chem 4A & Math 1A} >>> {Physics 7A & Chem 4B & Math 1B} >>> {Physics 7B & Math 53} >>> {Chem 120A & Math 54} >>> Chem 120B >>> Chem 125</p>
<p>Chemical Biology</p>
<p>Chem 4A >>> Chem 4B >>> Chem 112A >>> {Chem 112B & Bio 1A} >>> Chem 135 >>> {MCB 110 & MCB 110L}</p>
<p>The entire ChemE degree is a course prerequisite chain</p>
<p>^ The longest chain in ChemE that I know of is for the biotechnology concentration: 4A => 4B => 140 => 141,150A => 142, 150B => 154, 162, 160, 170A, 170L => 170B.</p>
<p>This is 7 steps.</p>
