This page lists all of the free web services provided by RogerHub. I add to it occasionally when I make new things, and I clean up old pages if they are unpopular. My goal is to fill up this page with magical useful things, but work and school get in the way. Anyway, please enjoy whatever I do have for you.

A university admissions calculator built using stastical models derived from the UCOP Statfinder program. This calculator will tell you if students similar to you got into University of California schools in the past.
