Registration follows the pattern shown above.
It opens with graduate and professional student registration, which starts on a Wednesday and lasts 2 days. Then, undergraduate registration starts on the following Friday, with 3 days of windows for seniors. Each senior window is open to all seniors. The remaining one-day windows are for the other academic classes, which register in turn. Academic classes are sub-divided into five groups, each according to the last two digits of students' social security numbers.
