#  The Prefresher 

 



 To prepare for grad school, all incoming Government PhD Students should take the [Math Prefresher](https://projects.iq.harvard.edu/prefresher/home). The *Math Prefresher* is a two week refresher which refreshes your math and offers you an introduction to installing and using [R](https://www.r-project.org/).

 Beyond that, it offers a crucial chance to get to know your cohort, some upper-Gs, and some members of the faculty.
