<p>Math 55 is a freshman class. It fulfills the prerequisites of quite a few other Harvard math classes, and cannot be taken for credit concurrently with other classes that cover the same ground. </p>

<p>A student who finishes Math 55 is well prepared to take various upper-division undergraduate math courses at Harvard, and will probably be a math major who ends up taking (Harvard) graduate-level math courses before finishing his undergraduate degree program. </p>
<p>If you’re admitted to Harvard and curious about Math 55, I guess you can try it out during next year’s shopping period. The shopping period is extended for students trying to find the right math class among Math 21, Math 23, Math 25, and, especially, Math 55.</p>
